'.. Minidisc is forever.'
Forever?, just wait until the magneto-optical head of your favourite recorder/player fails and you try to repair it/get it repaired...having a quick look on fleabay I note that they're relatively cheap on the used market so maybe it's not the problem now that it was when mine went fubar.
(RIP Minidisc, my portable music player format of choice for the better part of a decade..nowadays it's a Sandisk Clip Jam, 8GB onboard, 64GB microsd, so far proven to be nearly indestructible..)
