Erreur lecture TOC: pour pièces … ou réparation, la solution est probablement sur Reddit:

« .., give a TOC reading error and eject the minidisc, tried it with a brand new minidisc same problem, it would spin up try to read the TOC a couple of times then ejected the disc. I tried cleaning the lens but it didn't help. I then took a peek inside the mechanism and saw a few surface mount electrolytic capacitors which I immediately suspected them as those are the worst.

I separated the board from the mechanism and swapped all six 6.3V 100uF and two 10V 10uF with normal through hole capacitors soldered to the pads. After reassembling it read the TOC immediately after inserting the disc and it's working perfectly now, just finished recording my first minidisc ever! »



Conclusion
Traditionally MiniDisc has given journalists the heebeegeebees because it breaks hi-fi's most important rule--thou shalt not lose information. MD's data coding does precisely that, so most of the great and good of hi-fi scribbling were agin it from the start. But consider this--if the end product sounds good enough, does it really matter how it goes about the job? This is Sony's answer to MD's detractors, and it's a compelling one.
At ВЈ300 Sony's MDS-JE500 has much to recommend it, not least the MD format itself which is great to use--so durable it makes CDs feel like 78rpm gramophone records. MDs are really far easier to handle, store, and transport. And as far as sonics are concerned, even the most hardened hi-fi hack would have to admit that it's good. If I was forced to put my cards on the table and nominate cassette's rightful successor, then MiniDisc is it.


WORLD VERDICT * * * * (Actually 4 globes, Hi-Fi World's highest rating, Outstanding)
Impressive sound and unmatched convenience make it an excellent buy. Superb value for money.

What is MiniDisc?
MD is an optical disc in a protective case, about two thirds the size of a modern computer floppy disc. With the recording surface fully enclosed, MD is extremely durable, with a claimed life of up to one million recordings. It's also insensitive to shocks and extremely light and compact, making it ideal for mobile use. MD gives a playing time of up to 74 minutes in stereo or twice that in mono, and blank discs cost around ВЈ5 each at the moment. Although pre-recorded MiniDiscs are available they've yet to achieve widespread sales. However, an increasing number of new releases are now appearing on MD.
