Or similar models with the same spindle. Would the Playstation spring ball type be suitable for this. Or is there an exact type out there as I haven't found a site selling any. Mines got 1 broken tooth.
It is almost guaranteed that there are many, perhaps a dozen or more, models of Discman that use the same spindle platter. The difficulty is in finding the models. E-bay is your friend here. Because listings for other models have pictures and often enough the seller shows a picture of the Discman with the lid open. So we can see what kind of platter it has. So you have to Google up a list of other D-NE Discman players model numbers and systematically e-bay search them. Eventually you will find a cheap low cost "for parts broken" one that has the exact same spindle platter you need. To transplant and swap over. Something like that. (You millage may vary. Not responsible for resulting stress leading to mental breakdown and institutionalization when the prized replacement platter snaps in half during installation )
