ABSTRACT:
A cartridge type disk apparatus for recording and/or reproducing an information signal, by means of a recording head, on and from an information recording disk that is accommodated in a cartridge and mounted on the cartridge type disk apparatus together with the cartridge such that the information recording disk is located with a predetermined relationship with respect to the recording head. The apparatus comprises a chassis base, a disk cartridge support member disposed on the chassis base in the vicinity of the recording head for supporting the disk cartridge, and a mechanism for displacing the disk cartridge support member such that when the disk cartridge is inserted, the disk cartridge support member protrudes beyond the head to a support position wherein the disk cartridge support member supports the disk cartridge, and when the disk cartridge is mounted with a displacement in a direction perpendicular to a major surface of the disk cartridge, the disk cartridge support member displaces to a retreat position where it does not obstruct mounting of the disk cartridge.
