COMPUTER DISKETTE WITH INSERTABLE MULTI-PIECE MEDIA

摘要

A computer diskette system (10) utilizes a pair of partial disks (14, 16) which mate together to form a complete data storage disk that can be read in a conventional manner by a computer disk drive. When mated together, the partial disks are mounted in a diskette (12) that comprises a cartridge (18) for holding the partial disks and a hub (24) rotatably mounted in an opening in the lower wall of the cartridge. The hub (24) has a center hold for receiving a drive spindle of the computer disk drive and, within the cartridge, has an interlocking portion to which the partial disks can be attached. The hub and partial disks can have radially-extending interlocking elements (42, 44) that prevent the disks from slipping on the hub when it is being driven by the disk drive. The cartrige has an access door (20b) for inserting and removing the partial disks. A first one of the two partial disks contains conventional formatting information which identifies the locations of data on the second partial disk.
