No worries, time passed and MiniDisc never skyrocketed outside Japan, sadly. Also, there were “white label” devices that brands could buy readymade from some unknown companies and just print their name on and sell them. Don’t think Toshiba did that, they were toying with high density optical storage in the early 90s so probably they completely skipped MiniDisc iirc. The competition for digital in the 90s was amazing! Philips invented the dcc, a digital cassette where devices were backward compatible with the widely common analog cassettes but the information was digital. It was the Philips competitor of MiniDisc but failed badly because it was carrying the downsides of the tape while MiniDisc had the plus of the CD (ironically designed by Philips and Sony). And also the DAT was already there and with 100% lossless PCM.
