Abstract

A computer diskette system utilizes a pair of partial disks 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 that comprises a cartridge for holding the partial disks and a hub rotatably mounted in an opening in the lower wall of the cartridge. The hub 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 that prevent the disks from slipping on the hub when it is being driven by the disk drive. The cartridge has an access door 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. The second partial disk can then be used to store business contact information as one or more preselected files that are common to all such partial disks and that information can then be retrieved in a conventional manner using the formatting information contained on the first partial disk. A computer program can be used to access and use the data stored on the second partial disk. In another embodiment, the second partial disk attaches to the first partial disk which is permanently mounted on the hub.
