Abstract
An information storage device includes a cradle which can removably receive a cartridge that contains a rotatable hard disk. A read/write head is supported for movement adjacent the disk by a pivotal actuator arm. The cradle controls alignment of the head with the disk using feedback servo tracking. Servo parameters needed by the cradle to perform this tracking may be stored in a special wide track which is on the disk, and which may be a read-only track. Alternatively, the track may store updated firmware that can be loaded into the cradle. One approach to reading this special wide track is to effect servo tracking using default servo parameters. A different approach is to bias the actuator arm against a mechanical stop.
