text: I've now departed from this with the microcassette, simply because that is what Olympus did when they specified it, and other manufacturers such as Sony followed their lead. Within the tolerances of the machines, they are actually using the conventional ips speeds, but they are quoted in metric units on the speed change switches and in the owners' manuals, so I think that should be the primary measurement in the article too.

message: So for example, the Montgomery Ward catalogue of 1964 gives the playing time of 600', 900', 1200' and 1800' tapes as 2, 3, 4 and 6 hours respectively at 33/4 ips.
And it does too (p1262) but it's very misleading. It appears on a page with four tape recorders, three of which are stereo recorders capable of recording and playing in quarter-track mono mode, which gives the playing times quoted there. They are twice the normal playing times. Andrewa 03:14, 12 August 2005 (UTC)

message: I suggest renaming/moving this page to Audio tape specifications.  Length and thickness are not the only interesting specs.

message: I remember reading somewhere a while ago that the 3-inch-reel 1 7/8" ips speed "message tapes" mentioned in this article were popular in the 1950s and 1960s as an alternative to long-distance telephone calls, since the long-distance network of Ma Bell's (and other foreign phone cos.) yielded quite poor voice quality (due to the analog nature of the phone system at the time, and the now-crude technology used then to run it) at a much higher cost, compared to just sending a tape in the mail, which was much cheaper (and yielded a better quality of voice communication, although most definitely not in real time).  Was this the the main reason for using message tapes?  misternuvistor (talk) 13:22, 20 December 2012 (UTC)
