Talk:9-track tape

message: It's my recollection that 2400's with the 7-track option could only process 7-track tapes.--agr 14:24, 12 October 2006 (UTC)
thread_title: 2400 7-track option

message: This article Says that Media Mastr started manufacturing 9-track tape ("NineTrax" brand) in 2002 after Graham/eMag stopped.  Real 2 Reel Computer Tape, Inc. has a very minimal web page (modification date 2007-11-07) claiming to still be manufacturing NineTrax brand.  You can buy it here.
What I'm not sure of is if that's old stock or it's currently being manufactured.  71.41.210.146 (talk) 14:39, 15 March 2009 (UTC)

message: I have not been able to find any references to the IBM 2440 tape drive.  Does anyone have an authorative source for it?  If not, I will delete it.  John Sauter (talk) 04:50, 19 October 2014 (UTC)

message: The article states “...the capstan and head assemblies were always in contact with the tape, even during fast forward and rewind operations.”  However, GA22-6866-5 (referenced in the article) states in a footnote on page 51 “Rewind unload takes less time than rewind in the [IBM 2401] model 1 or 4 because tape is wound to load point at high speed.  Rewind requires reloading tape.  With models 2, 3, 5, 6 and 8, tape is reloaded during a rewind-unload at the end of high-speed rewind and rewound to load point at low speed; it is then unloaded again (rewind does not require final unloading).”
While it is clear from the text that the tape is not in the vacuum columns during high-speed rewind, it is less clear whether the tape remained in contact with the head assembly.  However, the picture on page 47 shows two high-speed rewind idlers.  They appear to guide the tape directly between the reels, bypassing the vacuum columns and the head assembly, which is lifted out of the way.  This isn't very good evidence, but I think it is good enough to alter the article to say that the capstan and head assemblies were always in contact with the tape except during high-speed rewind operations.  If there is no disagreement I will modify the article.  John Sauter (talk) 21:15, 25 May 2017 (UTC)

message: The article mentions inter-record gap and inter-block gap.  As well as I know, this is, more or less, right. From the hardware point of view, there are records. Hardware doesn't know if records are blocked. From the software point of view, there are records, blocks, and inter-block gap.  Similar to the confusion in networking between packet (software) and frame (hardware). Gah4 (talk) 02:19, 14 February 2023 (UTC)
thread_title:  blocks 

message: I thought the article might mention if there is a CRC or parity byte at the end of a block. I haven't thought about this in years, and this seemed a good place to look. Gah4 (talk) 02:20, 14 February 2023 (UTC)
