Abstract
A disc drive 20 includes a tray assembly 34 for positively seating and locking a cartridge 21 onto a spindle motor 82. The drive 20 includes heads 108, 110 mounted on a radial arm voice coil actuator assembly 112 and appropriate mechanisms including the arm control assembly 126 and the ratchet 124 and pawl projection 170 to ensure that the heads 108, 110 are properly loaded onto the disc 90 and that the cartridge 21 insertion and ejection process does not cause damage to the heads 108, 110 or the disc 90 contained in the cartridge 21. Further the drive 20 includes controls such as the cartridge load lever 32 and the release button 30 which are not exposed and cannot be accidentally tripped during data transfer operations.
