US Patent:

20060098323, May 11, 2006

Filed:

Nov 10, 2004

Appl. No.:

10/985443

Inventors:

Turguy Goker - Solana Beach CA, US
Hoa Le - Orange CA, US
Stephen Cooper - Costa Mesa CA, US

International Classification:

G11B 15/46

US Classification:

360073070, 360073080

Abstract:

A control system and method for operating a system comprising a host computer, a buffer, a tape drive and a tape is provided. The method includes writing data to the tape while the tape is traveling at a first speed; stopping the tape; determining an optimum second speed to drive the tape to travel; and, thereafter driving the tape to travel at the second speed while writing data to the tape.

International Classification:

G06F 5/14

US Classification:

710 57

Abstract:

A variable speed linear tape drive includes a driver portion for rotating a supply reel of a tape cartridge having storage media spooled therein, a motor coupled to rotate the driver portion, a controller configured to control the motor in accordance with a control algorithm, an interface for one or more of sending data to and receiving data from a host; and a buffer for storing one or more of data received from the host and data to be transmitted to the host, the buffer operable to supply a buffer fill level indication to the controller, wherein the control algorithm is operable to generate a difference between a target buffer fill level and the buffer fill level indication and adjust at least one of an angular velocity or an acceleration of the motor to reduce the difference.

G11B 5/008
G11B 20/12
G11B 5/41

Abstract:

A diagnostic tape () for use with a tape drive () having a tape head () includes a first tape section (A) and a second tape section (B). The first tape section (A) and the second tape section (B) are configured to move across the tape head () during use of the tape drive (). The first tape section (A) includes a first patterned data code (A) that is indicative of a first spacing between the tape head () and the first tape section (A). The second tape section (B) includes a second patterned data code (B) that is indicative of a second spacing between the tape head () and the second tape section (B). The second patterned data code (B) is different than the first patterned data code (A). The diagnostic tape () can further include a tape head cleaning section (F) including abrasive material () that is configured to move across the tape head () to clean the tape head ().

Abstract:

A tape layout module for determining a tape layout allocation strategy for laying out data on tape, the data being organized into a plurality of fixed-size subdata sets with each of the plurality of subdata sets including a plurality of codeword interleaves, the tape including a plurality of media defect characteristics, includes a tape layout optimization system including a processor that receives information on the plurality of media defect characteristics. The tape layout optimization system determines the tape layout allocation strategy based at least in part on at least one of the plurality of media defect characteristics. Additionally, the tape layout optimization system can determine the tape layout allocation strategy further based on distance spectra between pairs of the plurality of codeword interleaves. Further, the tape layout optimization system can determine the tape layout allocation strategy by selectively utilizing at least one tape layout parameter.
