A storage media is disclosed and comprises a storage body and a readable indelible mark formed in the body such that portions thereof are indelibly altered. The mark is read by writing first data to the body in the region of the mark, and reading second data from the body in such region. The written first data is not accepted where the portions of the body are indelibly altered. Accordingly, the read second data corresponds to the written first data with segments thereof missing. The missing segments of the first data correspond to the portions of the body indelibly altered. In a preferred embodiment, the storage media comprises a magnetic rotatable disk having a substantially planar substrate and a magnetizable layer deposited thereon. The reading and writing are therefore performed magnetically.

Readable indelible mark on storage media

A head loading apparatus for a disk drive device is disclosed that limits the velocity of the heads during loading of the heads onto the surface of a data storage medium. The apparatus is characterized by varying a voice coil current or voltage during the head loading process. The varying current or voltage nudges read-write heads off of a load ramp and onto the surface of a data storage medium.

Velocity limited loading of read heads onto disk drive media

A head loading and parking apparatus for a disk drive device is disclosed that is characterized by varying a voice coil current and voltage during a head loading process. The varying voltage nudges read-write heads off of a load ramp and onto the surface of a data storage medium. Peak power is controlled by selectively turning off portions of the electronic system.
