US Classification:

360 75, 360 51, 360 7708

Abstract:

A method for writing servo information onto a disk of a hard disk drive with a servo writer. The disk has a circumferential index and a band of servo reference tracks. The circumferential index is detected from a clock signal generated from a clock track of the disk. The reference tracks include radial indices. A spiral servo pattern is written upon the detection of the circumferential index and a radial index. The servo writer includes a phase detector that detects changes in the relative position of the circumferential and radial indices and a delay circuit that delays the clock signal to offset such changes.

Abstract:

A security system includes an electronic lock and an electronic key. The electronic key holds identification data that notifies the lock of the key's functional type and the locks that the key is authorized to open. In one embodiment, circuitry in the lock checks whether an inserted key holds an access code that is more recent than a corresponding access code stored in the lock, indicating that the data on the inserted key is more current than the data stored in the lock. The lock is then automatically reprogrammed with the data stored in the inserted key.
