US Patent:

20030043710, Mar 6, 2003

Filed:

Aug 30, 2001

Appl. No.:

09/943102

Inventors:

Boyd Shelton - N. Ogden UT, US
Charlie Monroe - Longmont CO, US

International Classification:

G11B007/005
G11B007/24

US Classification:

369/044340, 369/275300, 369/047350

Abstract:

A storage medium is provided having a relatively large number of relatively small servo sectors. The storage medium includes a plurality of tracks. Each track includes a plurality of data sectors and a plurality of servo sectors. Each servo sector includes a plurality of servo marks and a synchronization gap. A plurality of first servo sectors includes a synchronization gap having a first length and a plurality of second servo sectors includes a synchronization gap having a second length. The first length is different from the second length, whereby, an unsynchronized reading device may recognize the longer synchronization gap and synchronize to the servo sector and a synchronized reading device may remain synchronized by recognizing the shorter synchronization gap.

International Classification:

G11B 1504

US Classification:

360 60

Abstract:

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.

8/058288

Inventors:

Michael A. Blatchley - Longmont CO

Harlan Mathews - Boulder CO

Assignee:

Maxtor Corporation - Longmont CO

International Classification:

G11B 509

US Classification:

360 46

Abstract:

A pulse detection sensing system which provides an output signal only when a maximum voltage peak is detected. The system has a comparator which generates a comparator output signal when an output signal generated by the transducer of the system is equal to or greater than a threshold signal. The comparator is coupled to a peak follower and a sample/hold circuit which increases the voltage of the threshold signal to the level of the head output signal when the output signal attains a zero slope and has equaled or exceeded the set threshold value.
