I can offer some information regarding consumer level portable minidiscs.

('ATRAC') It's interesting to note tho that Dragon Systems recommends Sony's MZ-R50 as the "dictation recorder for their speech recognition system." > > I need to take into account transferability to computer (eg the Kay system) > for analysis - from the descriptions I've seen all the digital systems seem > to have digital output on optical channel only - is there equipment > available to convert this to standard input interfaces? You mention portable recording equipment-Most minidisc portables I've seen do not have digital output (they do have digital optical inputs tho) but regular line outs. Most consumer level DAT machines should have electrical digital output in the SPDIF format, which some newer PC sounds cards support so you can transfer digital data directly, bypassing DAC/ADC stages. If you do run across optical output on minidisc *decks*, they are probably TOS-link style, for which there are TOS to SPDIF converters. Check out the minidisc webpage for more info.. Robert McGill is running a new version of LISTSERV (1.8d on Windows NT). Information is available on the WEB at
