Location and centering of a digital video cartridge within a disk drive

摘要

A disk drive has a support structure for maintaining alignment between a removable hard disk cartridge and the disk drive. Particularly, the disk drive and support structure are for use with recording and archiving digital video and other data. The support structure makes use of a series of engagable surfaces on both the cartridge and drive. These fixed surfaces can fully determine the position of the cartridge within the drive so as to avoid interference of the cartridge housing with the rotating disk, movable head support structures, and the like. Preferably, alternative insertion surfaces may be provided on the cartridge and disk drive housings to slidingly engage each other during manual insertion of the cartridge so as to promote normal engagement and disengagement of the spindle drive and disk hub structures.
