R-DAT and S-DAT[edit]

When DAT first come out, I believe there was two formats: the Helical format we all know about (called R-DAT), and a Linear format called S-DAT. Probably the most famous reference in popular culture is in Neo Genesis Evangelion as Shinji's portable music player so it's a bit of a disapointment it's not mentioned at all here. Perhaps someone who knows some links about this can update the page? StaticSan (talk) 05:14, 18 November 2008 (UTC)


Your article says Sony introduced DAT or Digital Audio Tape in 1987. I'm not certain of the timeline. But I recall hearing about Digital Audio Tape in the media. Very shortly after it was announced as a technological feat and it was released as a Product in the rest of the world.

The Music Recording industry in the United States fearing that people would copy the material, and have 'masters' they could copy large quantities of would reduce the profits of the recording industry. The Music Recording Industry went to the United States Government and said, "if this is allowed, it will put us out of business"

The United States Government responded to the MultiMillion Dollar Recording Industry. The government issued a moratorium on the importation of Digital Audio Tape for SEVEN(7) YEARS. Allowing the Music Recording Industry time to figure out how to incorprate something into equipment sold in this country to prevent the wholesale copying of their copyrighted material.

I'm not certain, but i believe that the Moratorium was issued in 1979 and probably lasted until 1986, or so. Which put the people in this country who worked in the audio equipment field seven (7) years behind the rest of the world. This is as far as i know the first time that the United States Government has prevented Technological Progress by issuing a Law. -- 17:13, 7 October 2005 (UTC) by Nick Sues Oct 7. 2005

Explanation of my edits[edit]

I just thought I'd give a few notes on my changes. I added some information here and there, moved a few sections around, and added section/subsection titles so that there would be a TOC and the article would be easier to navigate. I think this goes quite a way to bringing the article up to standard. I'm not sure whether people will think that I went overboard on the subsections, but my thinking was that I would rather have too many discrete subsections than too few, since by having subsections, the article becomes a little less unwieldy for people to edit. If there is a consensus though that we don't want as many sections, feel free to remove them, I won't be offended. Kadin2048 20:41, 17 March 2006 (UTC)

Copyright violation?[edit]

The entire History section seems lifted word-for-word from

More like the other way around. There seems to be a lot of websites out there that copy Wikipedia's content word-for-word, considering the public-domain nature of Wikipedia's content. I know that that the site you mentioned has copied from Wikipedia, since I wrote some of that content here, especially regarding the "Predecessor Formats" section... misternuvistor 06:47, 2 June 2006 (UTC)

Usages: Radio??[edit]

Ummm...isn't/wasn't DAT the format of "carts" widely used to this day in radio broadcasting for station ID's, jingles, commercials, etc.?

Nope: They used MiniDisc's for that (Sorry for not signing, forgot where to find "Tildes" on a MAC-AZERTY-keybord. —Preceding unsigned comment added by (talk) 22:15, 24 August 2010 (UTC)

Missing information[edit]

This article fails to mention if the cassettes are single or double sided! -- 04:55, 5 February 2007 (UTC)

They are single-sided, much like a videocassette. I'll add this info to the article, if it hasn't been already... misternuvistor 12:00, 5 February 2007 (UTC)
Of course all cassettes are single 'sided' (only the side of the tape facing outwards can be used), but some divide that side into two regions to be used when the tape mechanism moves the tape in different directions. Alan Davies (talk) 16:26, 9 July 2011 (UTC)
Of course to you but somewhere it needs to be explained to the dear reader that when you flip over a cassette, you're not using the back side of the tape, you're using different tracks on the front side and in the other direction. I don't see such an explanation here and I don't see it in the vast reaches of Compact Cassette. --Kvng (talk) 16:55, 11 July 2011 (UTC)

encoding issues[edit]

Does anyone know what sort of error detection/correction algorithms were used in DAT? There had to have been some, somewhere--parity bits, block coding, or something. 01:23, 17 May 2007 (UTC) M Kinsler

Photo of Recording Head please[edit]

I'd like to see a photo of the recording head added to this article. I've never seen an audio player with a "spinning head" before, and I'm curious how it looks. - Theaveng 14:42, 9 October 2007 (UTC)

Merge content to/from AHRA article[edit]

I created an Anti-DAT lobbying section, moved some content into it, and used a 1989 Rolling Stone report for a source. This source provides some info not yet present in Audio Home Recording Act#History and Legislative Background. Could someone merge it into there? Also, there is material in Audio Home Recording Act#History and Legislative Background that could stand to be merged into here. Thanks. —mjb 08:34, 25 October 2007 (UTC)

"Archived audio" section[edit]

The user who originally added this in 2007 has just reverted it back in, offering personal anecdotes as evidence. The lack of reliable sources for this section, along with the evident problems with it being soapboxing and original research, seem to make its removal a pretty obvious choice.

the cost of the royalties in a DAT tape[edit]

Does anyone know the order of magnitude of these costs ? —Preceding unsigned comment added by Cold Light (talkcontribs) 21:26, 28 February 2009 (UTC)

anti-DAT lobbying[edit]

This sentence makes no sense to me: "A National Bureau of Standards study showed that not only were the effects plainly audible, but that it wasn't even effective at preventing copying. Thus the audible pollution of prerecorded music was averted." I suspect that it should say "plainly inaudible" but then maybe I am missing something. If the effects were plainly audible, I would think that would rather discourage home recording. Wschart (talk) 21:59, 26 April 2010 (UTC)

compact audio cassette[edit]

I don't think this statement about magnetic audio cassettes is accurate.

Like most formats of videocassette, a DAT cassette may only be recorded on one side, unlike an analog compact audio cassette.

Compact audio cassettes accept recording on only one side of the media. The width of that one side is divided into four tracks. Two are used for recording and playback in one direction. The other two are used in the opposite direction.

Pdesj (talk) 17:17, 13 September 2010 (UTC)

Your technical understanding is correct. The sentence is referring not to two sides of the audio tape but two sides of the cassette. You flip an analog Compact Cassette over to the other side to access the other half of the tape. --Kvng (talk) 18:09, 13 September 2010 (UTC)

CopyCode needs its own article[edit]

The story behind CBS's CopyCode is fascinating, and has many authoritative references and Congressional reports. It is worthy of its own article —Preceding unsigned comment added by (talk) 00:09, 13 February 2011 (UTC)

Citation needed[edit]

I see this note frequently toward the end of the article. I'm not sure about the person who wrote the information in question, but I've seen DAT in use recently on commercial productions and in TV stations. It's also obvious that the short lives the obsoleted DAT decks have in relation to audio archives are is huge problem. Also, I was never a DAT-head (concert bootlegger) but I was witness in the thick of it. Being able to put a battery operated digital recorder with mic preamps & line inputs under your coat was a blessing in a time when there just weren't CD recorders. How do you cite your own observation? Wado1942 (talk) 03:31, 22 May 2011 (UTC)wado1942

You don't. It's Original Research (talk) 17:20, 21 November 2011 (UTC)
