DATA STORAGE CASE HAVING A WRITE/PROTECT ASSEMBLY

摘要

A data strage case having a write/protect assembly includes a main body of the cartridge, a plurality of detection holes formed in the lateral sides and a pair of flat sides of the main body of the cartridge at a corner of the front side of the main body of the cartridge looking in the direction of insertion of the main body of the cartridge into the interior of the recording/reproducing apparatus, and mating detection elements intruded into these detection holes. The main body of the cartridge accommodates a disk-shaped recording medium, on which information signals can be recorded, and has apertures by which the signal recording section of the disk-shaped recording medium is exposed to outside. The mating detection elements may be moved between a first position and a second position within the detection holes.
