DISK DRIVE WITH SPICULE MEMBER

A device for aligning a disk contained in a cartridge with a motor and transducer of a disk drive is disclosed. A record disk contained within a rigid apertured cartridge is inserted into a disk drive for use with that disk drive. Insertion of the cartridge into the disk drive causes engagement of a reference surface of the cartridge with a reference surface of a spicule member contained within the disk drive. The spicule member carries the transducer and drive spindle of the disk drive. The spicule member also contains a clamping device which ensures proper engagement of the cartridge reference surface and the spicule reference surface. The result is the proper alignment between the disk contained in the rigid cartridge and the transducer and motor spindle carried by the spicule member.
