ABSTRACT:
In a large-capacity flexible disk having a case accommodating a magnetic disk medium, the case is provided with a single large-capacity identifier hole formed in the vicinity of a write protection hole to discriminate the large-capacity flexible disk from a small-capacity flexible disk. The large-capacity flexible disk is one of a plurality of types having storage capacities different from one another. The case is further provided with type identifier holes selectively formed to identify the type of the large-capacity flexible disk so that the type of the large-capacity flexible disk can be identified with reference to the number and the position of the type identifier holes. A high-density type flexible disk drive, moreover, is provided with a large-capacity detecting switch at a position corresponding to the large-capacity identifier hole.
