4 = 3.8?[edit]

Anyone know why the Four millimeter tape is only 3.8 millimeters? —Jfingers88 23:21, 14 July 2006 (UTC)

I got the spec from the Digital Data Storage page. —Austin Murphy 21:18, 16 July 2006 (UTC)
In 1972 there were a few systems that used a 0.150" tape cartridge, 3M/Scotch DC-150A. DECtapeII, HP85, and maybe others. http://www.athana.com/html/minicart.htmlAustin Murphy 20:05, 25 August 2006 (UTC)

There is no difference between "eighth inch" and "four millimeter" tape. Both types are derived from standard cassette tape width, which is only nominally one eighth inch wide, but is actually 0.150 inches or 3.81 mm wide. --Blainster 16:26, 27 March 2007 (UTC)

First library?[edit]

Change the layout a bit?[edit]

Anybody mind if I play with the layout, maybe change the header to use {{tnavbar}} so it can be hidden, and edited easily? Like {{IT giants}} —Wikibarista 09:27, 25 September 2006 (UTC)

That's a good idea. -- Austin Murphy 14:20, 25 September 2006 (UTC)


Current formatting makes the table really unreadable to me. It's a crowd of anybody-ever-heard-of-it formats and it is so hard for a reader to spot the popular and important formats (like LTO). Should it be aimed at tape history maniacs or maybe at readers that would like to learn something useful? Tell me if this list of american citizens is useful: Byron Brown, Susan Buczak, Elizabeth Bunich, Colleen Bush, George Bush, Randy Bushover, Michael Buyer. --Kubanczyk 12:36, 5 March 2007 (UTC)

New Formats[edit]

These formats need wikipages


These are "Instrumentation" formats and probably do not belong on the "data" template:

  • 19 mm - helical - Ampex DIS (DD-2) [2]
  • 25.4 mm - transverse scan - Ampex DCRsi [3]

New Layout[edit]

I changed the layout so it uses the Navbox template. I copied the look of Template:Video storage formats. I'm moderately satisfied with the results. I wish there was a Navbox template that had groups and columns. -- Austin Murphy (talk) 14:35, 4 January 2008 (UTC)
