ABSTRACT:
A disk drive with removable cartridges that is designed for laptop and notebook sized computers which are battery powered. The drive includes a disk cartridge that upon insertion into the disk drive is split open to move an underside portion down over a disk drive spindle where the disk, having been released by the splitting of the cartridge engages the spindle for rotation. The spindle is mounted in the drive in a fixed location so that loading of disks thereon is repeatable and interchangeable and do not change with wear of a spindle elevating mechanism. The read/write heads on their actuator arms extend through an opening in the back of the cartridge formed when the cartridge is split. When ejected, the cartridge seals about the disk to prevent contamination thereof and to assure a long life in harsh environments. The cartridge may include an inner door that is opened upon cartridge insertion to provide clearance for the heads and actuator arms.
