Random Access Time To Data Stored On Lto Tape By Incorporating Stacked Cartridge Memory (Cm) Modules

View page
US Patent:
7111135, Sep 19, 2006
Filed:
Jun 13, 2003
Appl. No.:
10/461627
Inventors:
Roger Javier Justo - Tucson AZ, US
Arturo Avila Mojica - Tucson AZ, US
Assignee:
International Business Machines Corporation - Armonk NY
International Classification:
G06F 12/16
US Classification:
711162, 711161, 360 721, 360132, 360134
Abstract:
A tape cartridge having dual cartridge memory modules to provide memory redundancy, and a method and apparatus for providing redundancy of cartridge memory information within a tape cartridge. The tape cartridge comprises at least first and second cartridge memory modules, each of which stores an identical set of critical information. Each of the first and second cartridge memory modules includes enough critical information to recover from a failure of either of the cartridge memory modules. The method comprises the steps of providing at least two cartridge memory modules in the tape cartridge, and storing an identical set of critical information in each of the two cartridge memory modules. Each of the two cartridge memory modules includes enough critical information to recover from a failure of either cartridge memory module. In a preferred embodiment, the CM modules are stacked one on top of another and increase the amount of space available for tape directory storage.

Fast Forward Magnetic Tape Cartridge At First Mount

View page
US Patent:
7719782, May 18, 2010
Filed:
Jan 7, 2009
Appl. No.:
12/349661
Inventors:
Allen Keith Bates - Tucson AZ, US
Shawn Owen Brume - Tucson AZ, US
Nhan Xuan Bui - Tucson AZ, US
Joel Hsien-Li Chen - Tucson AZ, US
Eric Rolf Christensen - Tucson AZ, US
Roger Javier Justo - Tucson AZ, US
Daniel James Winarski - Tucson AZ, US
Assignee:
International Business Machines Corporation - Armonk NY
International Classification:
G11B 15/20
US Classification:
360 69
Abstract:
Handling a magnetic tape cartridge comprises the steps of reading cartridge mount information from the cartridge memory; determining from the cartridge mount information whether the present mount is the first mount of the magnetic tape cartridge; and if so, fast forward and rewind the magnetic tape of the magnetic tape cartridge, e. g. , the fast forward is to end of tape (EOT) and the rewind is to beginning of tape (BOT). Alternatively, if the cartridge mount information indicates the present mount is the first mount of the magnetic tape cartridge; monitoring input/output with respect to the magnetic tape cartridge for write errors during the mount; determining whether the number of monitored write errors meets a predetermined threshold; and if so, fast forward and rewind the magnetic tape of the magnetic tape cartridge.

Method And Apparatus For Controlling Data Rate Of A Tape Drive

View page
US Patent:
7796354, Sep 14, 2010
Filed:
Oct 16, 2007
Appl. No.:
11/873207
Inventors:
Roger J. Justo - Tucson AZ, US
Assignee:
International Business Machines Corporation - Armonk NY
International Classification:
G11B 15/12
US Classification:
360 61, 360 31, 360 60, 360 71
Abstract:
A method for controlling data rate of a tape drive is disclosed. The tape drive is connected to a computer system. The tape drive stores data by dividing the data into multiple codeword quads (CQs). A local memory within the tape drive includes drive to iteratively monitor data rate during write operations. If a number of CQ skips exceeds a pre-defined threshold value, the drive code reduces a maximum allowable data rate of the tape drive.

Positioning Coarse Servo Actuator Of Tape Servo System To Allow Fine Servo Actuator To Follow Tape Shift Excursions

View page
US Patent:
8027121, Sep 27, 2011
Filed:
Nov 4, 2009
Appl. No.:
12/612403
Inventors:
Armando Jesus Argumedo - Tucson AZ, US
Nhan Xuan Bui - Tucson AZ, US
Reed Alan Hancock - Tucson AZ, US
Roger Javier Justo - Tucson AZ, US
Angeliki Pantazi - Thalwil, CH
Assignee:
International Business Machines Corporation - Armonk NY
International Classification:
G11B 5/584
US Classification:
360 7712
Abstract:
Methods, servo systems, and data storage drives follow the lateral shift excursions of longitudinal tape, for example, from flangeless tape guides. A servo sensor is configured to sense lateral position of a tape head with respect to longitudinal servo tracks of the tape, a fine actuator is configured to translate the head laterally, and a coarse actuator is configured to translate the fine actuator laterally. Position error is determined between the head and a desired position related to the servo track, and the fine actuator operated to translate the head laterally to reduce the position error. In the embodiment, lateral shift excursion is sensed from the position error, and the coarse actuator is positioned substantially at a midpoint of the lateral shift excursion. Thus, the fine actuator follows the lateral shift excursions, while the coarse actuator remains at the midpoint.

US Patent:
20140063649, Mar 6, 2014
Filed:
Aug 28, 2012
Appl. No.:
13/596876
Inventors:
Nhan Xuan BUI - Tucson AZ, US
Kevin Bruce Judd - Tucson AZ, US
Roger Javier Justo - Tucson AZ, US
Hirokazu Nakayama - Fujisawa, JP
Tomoko Taketomi - Yamato, JP
Assignee:
INTERNATIONAL BUSINESS MACHINES CORPORATION - Armonk NY
International Classification:
G11B 5/584
US Classification:
360 7712
Abstract:
A maximum velocity is dynamically determined during a tape drive operation to obtain a statistical standard deviation of a position error signal (PES) that yields an amount of stopwrite (SW) operations that avoids backhitching. The tape velocity is adjusted to the maximum velocity.

Optical Disk Players Having Readback Circuits With Noise Rejection And Read Signal Retiming

View page
US Patent:
51650894, Nov 17, 1992
Filed:
Oct 1, 1990
Appl. No.:
7/591160
Inventors:
Glen A. Jaquette - Tucson AZ
Roger J. Justo - Tucson AZ
Assignee:
International Business Machines Corporation - Armonk NY
International Classification:
H04N 576
US Classification:
369 59
Abstract:
In an optical disk player, such as for a magnetooptic player, wherein the data recorded on the optical medium are at recording at such high densities then intersymbol interference causes the peaks of the readback signals to become closer together resulting in phase errors. A transition selecting means is operative to select a transition indicated by the readback signal or a substitute transition indicated by a timed delay means generates a signal based upon the immediately preceding transition received from optical medium. Various embodiments of the invention are illustrated.
