GlobalFoundries Assigned Three Patents

Reading method for linear tape open
GlobalFoundries, Inc., Grand Cayman, Cayman Islands (Patent Assignee) with International Business Machines Corporation, Armonk, NY, (Patent Appliquant), has been assigned a patent (9,183,878) developed by Cherubini, Giovanni, Furrer, Simeon, Jelitto, Jens, and Lantz, Mark A., Rueschlikon, Switzerland, for a “reading method for linear tape open.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”A method for operating a tape storage system includes simultaneously receiving readback signals from a set of data readers reading from data tracks of a set of adjacent data tracks extending along a longitudinal extension of a tape storage medium. Each data track has a width and each data reader has a width that exceeds the width of a data track. In the readback signal, of one of the data readers of the set a simultaneous presence of two defined waveforms is detected stemming from two different servo patterns arranged in servo sections of adjacent data tracks of the set. At least one of lateral position, velocity, gain and timing information is derived from a measure of the energy of the two defined waveforms detected in the readback signal of the data reader and applying this information in the operation of the tape storage system.“

The patent application was filed on January 29, 2015 (14/608,508).

Locating data stored on magnetic medium
GlobalFoundries (name on the original document: “GLOBALGOUNDRIES”) U.S. 2 LLC, Hopewell Junction, NY (Patent Assignee) with International Business Machines Corporation (Patent Appliquant), has been assigned a patent (9,183,851), developed by Bates, Allen K., Bui, Nhan X., and Winarski, Daniel J., Tucson, AZ, for a “locating data stored on a magnetic medium.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”A set of lateral positions, of the magnetic medium with respect to the tape reel and a set of longitudinal positions of the magnetic medium with respect to the beginning of the magnetic medium as the magnetic medium comes off the first tape reel, are identified. A record is stored, on a non-volatile storage medium, of the set of lateral positions of the magnetic medium and the set of longitudinal positions of the magnetic medium. The record, of the set of lateral positions of the magnetic medium and the set of longitudinal positions of the magnetic medium as the magnetic medium comes off a second tape reel, is read. A tape head is moved laterally, to the lateral positions in response to the reading of the record of the set of lateral positions of the magnetic medium and the set of longitudinal positions of the magnetic medium.“

The patent application was filed on October 9, 2013 (14/049,278).
