ABSTRACT:
A disk supporting device has a spacer member which is placed close to the rim of a disk stored within a cartridge, and gently holds the rim of disk while the apparatus is put out of use; and a spacer releasing mechanism which, when the apparatus is put to use, is activated by a lever for opening/closing a shutter placed outside the cartridge, to displace the spacer member away from the disk in a radial direction of disk to separate the former from the latter. Further, the spacer member is so formed as to have a groove in the form of a rectangular indent on a side opposite to the disk for holding the latter. Through this constitution it is possible to obtain a disk supporting device which does not change its position with respect to the cartridge base whether the apparatus is put to use or out of use, and to produce a cartridge on the whole uniformly thin and allowing a good productivity.
