Servo Writer Providing A Pre-Writing, Longitudinal Magnetic Bias In A Magnetically Unoriented Tape Supply
US Patent:
7986485, Jul 26, 2011
Filed:
Mar 31, 2009
Appl. No.:
12/414954
Inventors:
Kevin D. Mckinstry - Denver CO, US

Assignee:
Oracle America, Inc. - Redwood City CA
International Classification:
G11B 21/02, G11B 5/03, G11B 5/584
US Classification:
360 75, 360 66, 360 7712
Abstract:
A servo writing method is provided for use with unoriented magnetic tape media. A biasing zone is formed, such as between a pair of permanent block or disk magnets, with a strong DC magnetic field that is substantially free of perpendicular components. The method includes feeding the tape through the magnetic biasing zone to form a longitudinal magnetic bias in the magnetic layer of the tape media. The method includes using a write head to write a servo pattern on the tape media after the forming of the longitudinal magnetic bias in the tape media, and the servo pattern produces an output that is substantially symmetric with high amplitudes. In one embodiment, the biasing zone is formed or defined as the gap between first and second magnetic assemblies oriented with a single direction of magnetization, such as in the same direction as the tape travel through the biasing zone.

Assignee:
Sun Microsystems Inc. - Santa Clara CA
International Classification:
G11B 23/30
US Classification:
360 69
Abstract:
A tape drive system for a tape cartridge including a tape and wireless identification tag may read information from the wireless identification tag and write the information to the tape. The tape drive system may toggle a bit stored on the wireless identification tag to indicate that the information has been written to the tape. The information may include tape initialization information.
Tuneable Radio-Frequency Identification Tag Reader And Method Of Reading Such A Tag
US Patent:
7933553, Apr 26, 2011
Filed:
Dec 6, 2007
Appl. No.:
11/951421
Inventors:
Steven M. Kientz - Westminster CO, US
Assignee:
Oracle America, Inc. - Redwood City CA
International Classification:
H04B 5/00
US Classification:
455 411, 455 77, 455 87, 4551501, 455120, 3405721
Abstract:
A radio-frequency identification (RFID) system is provided that includes an RFID reader that is provided with a capacitor apparatus or circuit that may be used to tune the transmitter to a different frequency to improve communication with an RFID tag. The frequency may be changed by the capacitor circuit automatically providing a different capacitance output to the RFID reader. A tape drive reader and magnetic tape cartridge may be provided in combination with such an RFID system. A method is disclosed for reading a data packet stored on an RFID tag by a reader that can be adjusted by changing the capacitance provided to the RFID reader.
Data Storage Tape For Minimized Damage
US Patent:
8014102, Sep 6, 2011
Filed:
Aug 28, 2007
Appl. No.:
11/845881
Inventors:
Steven M. Kientz - Westminster CO, US
Mark L. Watson - Louisville CO, US
Mark L. Watson - Louisville CO, US
Assignee:
Oracle America, Inc. - Redwood City CA
International Classification:
G11B 15/18, G11B 23/08
US Classification:
360132, 360134
Abstract:
A data storage device has a cartridge with tape having data and landing zones. One of the landing zones is aligned with a head during stopping of advancement of the tape to minimize damage. A data storage system is provided with a data storage device with data and landing zones, a read/write head, a motor for driving the tape and a processor for identifying the landing zone locations. A method for minimizing damage to data tape conveys base film along a coating head while intermittently dispensing a magnetic layer and a rougher coating layer to form landing zones. A method for minimizing damage to data storage tape provides a cassette with tape having intermittent data and non-data regions, that is inserted into a tape drive and a read or write function is performed. The tape is advanced to align a non-data region with a head and advancement is discontinued.
Method Of Calibrating Data Readers Relative To Servo Readers
US Patent:

Assignee:
ORACLE INTERNATIONAL CORPORATION - Redwood City CA
International Classification:
G11B 27/36, G11B 5/02
US Classification:
360 31, 360 55, G9B 27052, G9B 5026
Abstract:
A method of calibrating a servo reader and a read/write head for a data storage tape machine that reads and writes data to a data storage tape. The data storage tape has a servo pattern that is recorded on the tape in a known location. The servo pattern is used to provide precise position information for the data storage tape. According to the method, data is recorded on the data storage tape and the location of the data storage track is read. The location of the data storage tape is compared to the known location of the servo pattern to establish a reader offset value. The data storage tape machine is updated based upon the reader offset value to adjust the position of the read/write head.
Band Identification Using A Single C-Core Servo Write Head For Timing Based Servo Patterns
US Patent:
6934115, Aug 23, 2005
Filed:

Assignee:
Storage Technology Corporation - Louisville CO
International Classification:
G11B005/584, G11B021/02, G11B005/29
US Classification:
360 7712, 360 75, 360121
Abstract:
A timing based servo alignment system that uses a set of band identification marks to determine which data band is being currently read. The system uses a read module having a plurality of band identification read elements. The band identification read elements are placed on the read module such that each band identification read element is aligned only to the band identification marks when a corresponding data band is aligned to the data read element.
Reducing Tape Media Damage In Data Regions
US Patent:
7085091, Aug 1, 2006
Filed:
Dec 26, 2003
Appl. No.:
10/746383
Inventors:
Steven Michael Kientz - Westminster CO, US
Assignee:
Storage Technology Corporation - Louisville CO
International Classification:
G11B 15/48, G11B 5/584
US Classification:
360 741, 360 7712
Abstract:
A method and apparatus for reducing tape media edge damage in data regions. The present invention controls where popped strand occur by shifting the wrap turn around/stream points in the tape media to an unused region of tape. As data is written for the length of the tape, when a wrap turn around point is reached, the write current is shut off. However, the servo motors in the tape drive continue to stream the tape for a predefined distance past the turn around point. The head may then be moved transversely to acquire a new track. The tape may then be spooled in the reverse direction on the new track. When a wrap point is encountered, the write current may be turned on and the next track (wrap) may be written. This combination of steps may be repeated for each serpentine wrap on the tape.

Assignee:
Storage Technology Corporation - Louisville CO
International Classification:
G11B 23/107
US Classification:
360132
Abstract:
A method and system for transmitting tape cartridge information using a bi-axial tape cartridge antenna design. A contactless tape cartridge memory device is provided in which the memory device is accessible from multiple surfaces of the cartridge. A single flexible antenna surrounds the tape cartridge memory device. The antenna may be bent to fit within the corner of the tape cartridge, thus providing a parallel antenna surface to two locations on the cartridge, such as the front of the cartridge and the side or bottom of the cartridge. As a result, the memory device in the tape cartridge may be read when the cartridge is being inserted into the tape drive as well as while the cartridge is stored within the tape drive.
