Merge With Hard Disk Drive[edit]

While there is arguably a super-article, Disk Storage of which hard disk drives could be a subordinate article, this article is almost entirely about HDDs. For example, the recently added section Disk_storage#Standard_Disk_Sizes applies only to HDDs. Accordingly, I propose we should merge all HDD material from this article into Hard_Disk_Drive and if nothing is left delete this article (or leave a stub).

  • Your point about Disk Storage potentially being a super article (or an overview article) is well taken, as there are, for example, Zip, Jaz, REV, SyQuest, Floptical, various Floppy disc sizes and formats (from the original IBM 8 inch floppy, through the super floppies), and various other magnetic and optical disc drives. As well as audio records. Even flash drives, although they are not technically disc drives, in that they don't have rotating media, generally appear to the OS as a removable disc drive (using USB MSC drivers) and are mostly used as very large capacity "floppy discs". As 90+ percent of the article only relates to HDD content, and as I'm in favor of not having two articles covering essentially the same ground, merging the HDD content is very reasonable and I support it. Providing this article is left as a stub for expansion. I will add the summary paragraphs (with pointers to the main articles) once the merging is complete. — Becksguy (talk) 00:50, 19 January 2010 (UTC)
I disagree with the proposal for a merge and delete. Disk storage, as Becksguy points out, is so much more than just computer drives - I think that we will see the phasing out of memory sticks being recognised as disk drives, certainly my mobile phone is recognised as a phone and a mini pic of a phone is displayed in most progs when it is connected even though windows explorer still has it as a drive lol
I noticed that large block going in on HDD and was thinking about moving it into HDD article along with most of the section on HDD. I suggest that once that is done the rest of the document should be expanded to include the sections, optical disk, floppy disk etc with summaries and links to their main articles. It has been on my list of things to do since July but due to other things taking precedent I have only returned to editing properly in the last month.
I will keep an eye and move this to the top of my list for work to be carried out later today.

I have hidden the sections which are on HDD, and not general info, until we decide what to do with them.
Maybe I missed something, but I can find no hidden sections Tom94022 (talk) 03:54, 20 January 2010 (UTC)
  • Sorry, the hidden sections didn't show up in my change list, probably a buffering issue. Tom94022 (talk) 17:41, 20 January 2010 (UTC)
Chaos commented out some content, as done here. — Becksguy (talk) 10:13, 20 January 2010 (UTC)
I have also started to include more about CD's etc and will do more later or tomorrow.
Chaosdruid (talk) 21:51, 19 January 2010 (UTC)
Most of the things you are proposing to add have their own articles. That is why this article can be greatly reduced in size. Both Becksguy (talk and I support a stub. At this point do we have agreement amongst the three of us.? Tom94022 (talk) 03:54, 20 January 2010 (UTC)
  • I have been working offline on expanding the stub after merger of the HDD content. I placed my work done so far into a subpage User:Becksguy/Disk storage for any potential communal use. — Becksguy (talk) 10:06, 20 January 2010 (UTC)
As I noted in my recent edit, disk storage is not a subset of computer storage - there is a whole consumer side that needs to be covered. To that point, your categorization in the stub into removable and non-removable is not IMO particularly helpful. Tom94022 (talk) 17:41, 20 January 2010 (UTC)
The removable and non-removable categorization, if completed, would create some strange pairings, RAMAC and 1301 for example in Non Removable and most of the rest of the early IBM drives in removable. I suggest in the end the categorizations just be Hard disk drive, Floppy Disk Drives, and Optical Disk Drives and let the many flavors be linked off those pages. Other wise this is going to become a very long list. That further suggest that we just create a category, and put the category on each relevent page. Tom94022 (talk) 17:50, 20 January 2010 (UTC)
Good point on categorization. My draft was just a first quick attempt to get something down. And yes, it applies only to computer related disk storage, as that is a subset of disk storage generally. DEC RP04 & RP06 disc packs (similar to the IBM 3330 DASD) were also removable, but they were the system drive and therefore don't really fit today's understanding of removable in the sense of being secondary storage. — Becksguy (talk) 18:38, 20 January 2010 (UTC)
  • The section Disk_storage#Access_methods is horrible, very HDD oriented and incomplete at that. I intend to do major surgery there unless someone objects. Tom94022 (talk) 17:41, 20 January 2010 (UTC)
Agree. Access methods even apply to phonograph records. Might that section be an initial good candidate for merging the specific HDD related stuff? — Becksguy (talk) 18:53, 20 January 2010 (UTC)
The idea is like all articles on this vein - Each section has a brief description and a link to the main article on that topic.
At the moment this article is heading towards "Computer Disk Drives" not "Disk storage"Chaosdruid (talk) 02:48, 21 January 2010 (UTC)
disagree this article should be referenced to in the disk storage article along side "floppy disks" and "C.D.s"

I believe consensus has been reached that the merge should not occur. Removing request links. Mamyles (talk) 01:59, 24 April 2010 (UTC)
Actually the consensus seems to be to merge and it is well on its way, but removing the tag won't stop the merge. Tom94022 (talk) 04:25, 24 April 2010 (UTC)


This is going too far now. Disk storage is NOT just about computers...Tom you really need to consult and gain consensus before going so far demolishing an article Chaosdruid (talk) 02:47, 21 January 2010 (UTC)

I'm not sure what you are objecting to, please be more specific or better yet add to the article more material on disc storage for other than computer usage.
For example, disk storage is not about drums so I took it out.
For example, the section on Access Mechanisms is mainly about accessing computer disk storage and is incomplete/inaccurate at that. To your point it does not cover accessing audio or video in their players and probably shouldn't. So when it is fixed it is likely to be very small or gone.
  • That is, the portion on file systems is both inaccurate and incomplete and should be replaced with a single sentence linking to File systems, something like "Data on computer storage disks are organized into File systems which are the basis for access by the computing system." Tom94022 (talk) 18:18, 22 January 2010 (UTC)
For example, Disk storage is about audio (CD Audio) and video (DVD video, BR) storage and it is some what covered, some of which I added.
If you are objecting to my focus on digital then I suppose u can add or expand the material on phonographs and their records and the early analog video disks and players. As I suspected when we started this, getting rid of the HDD specific material will not leave much in the article. Tom94022 (talk) 18:20, 21 January 2010 (UTC)

Nuke Sections 2 thru 6 ?[edit]

The more I look at this article, the more I conclude we should nuke Sections 2 thru 6 and replace them with a single Section, Types of disk storage. The section in turn would list the major categories by with disc storage is subdivided, perhaps a short description and then a link to the appropriate article#section. At this point I can think of the following categories:

2. Types of disk storage {some generic words about the categorization of disk storage below}
Category Types
Medium: Rigid Magnetic, Flexible Magnetic or Rigid Magnetic are the primary disk storage media.
Access method: File system for computer storage, or ??? for audio and video.
Rotation: Typically Constant linear velocity for magnetic disk storage and Constant angular velocity for optical storage.
Size: Early disk storage devices, e.g. Early IBM disk storage, were separate cabinets but over time the sizes have evolved into standard Form Factors.
Mechanism: Early magnetic disk storage devices used Linear actuators; however, beginning 1975 magnetic storage devices began using rotary actuators[1] such that they are universal today. In a rotary actuator the heads move across the disk in an arc that approximates a radius. Optical disk storage devices use both Linear actuators and rotary actuators.
etc. TBD

I don't this list has to be exhaustive, just those key categories that significantly segment the market. For example, I did not include a category for Recording Method which would go into the distinction in disk storage between Analog recording and Digital recording because it seems like TMI. Note that in most cases I was able to link to an article so I didn't have to say much. In the case of "rotary actuator" where there is no article I put in a brief description. The idea is to keep this article short since so much of it is elsewhere. Comments?

Look out for possible copyright violations in this article[edit]

This article has been found to be edited by students of the Wikipedia:India Education Program project as part of their (still ongoing) course-work. Unfortunately, many of the edits in this program so far have been identified as plain copy-jobs from books and online resources and therefore had to be reverted. See the India Education Program talk page for details.

fixed-head disk[edit]

Information about fixed-head disk storage has apparently been removed from this disk storage article.

Is there some other article about fixed-head disks? Such fixed-head devices are alluded to in many Wikipedia articles -- paging, IBM System/360, 1ESS switch, OS/8, D-37C, Burroughs B2500, Autonetics Recomp II, etc. -- with a variety of names -- "fixed-head disk", "head-per-track disk drive", "head-per-track disk system", and probably other names as well.

In my opinion, it is misleading for "disk storage" in the above articles to link to this article -- which talks only about moving-head disk storage -- when those articles are actually referring to fixed-head disk storage.

Is there even a small section of some other article that discusses fixed-head disk storage, so I could point those links at something less misleading?

(Fixed-head storage has long been obsolete, but WP:RECENTISM and WP:DEFUNCTS imply that obsolescence alone is no reason not to have an article -- hence our articles on LaserDisc, IBM 305 RAMAC, disk pack, phonograph cylinder, etc.). --DavidCary (talk) 02:04, 24 January 2013 (UTC)

FWIW, Fixed-head disk drives are a subset of hard disk drives and IMO should be addressed as a section in the Hard disk drive article or perhaps in a separate article, but are not sufficiently notable to be added to this article. Tom94022 (talk) 17:46, 25 January 2013 (UTC)
Added a parapraph on head-per-track disk drives to the Hard disk drive article. That should be sufficient. I leave it to others to fix the links Tom94022 (talk) 21:12, 26 January 2013 (UTC)
