ABSTRACT:
The invention provides devices, systems, and methods for storing and archiving digital video and other data. A voice coil motor effects release of a removable hard disk cartridge from a disk drive. The voice coil motor is adapted for positioning a data transfer head along a recording surface of a rigid magnetic recording disk, and also moves the data heads from the recording surface to a "park" position away from the recording surface. This allows the disk to spin down within the cartridge while the cartridge is safely restrained inside the disk drive. Once it is safe to remove the cartridge from the drive, the voice coil motor can move beyond the park position to actuate a release linkage. The cartridge is typically expelled from the receiver of the disk drive by biasing springs. Hence, the present invention avoids the necessity to resort to a dedicated electromechanical actuator to expel the digital video cartridge from the disk drive.
