Western Digital Technologies Assigned Two Patents

Magnetic recording device having redundant servo readers and method for using same
Western Digital Technologies, Inc., San Jose, CA, has been assigned a patent (11935562) developed by Biskeborn, Robert G., Hollister, CA, Kobayashi, Masahito, and Noda, Junzo, Fujisawa, Japan, for “magnetic recording device having redundant servo readers and method for using same.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “The present disclosure is generally related to a tape drive comprising a tape head and a controller coupled to the tape head. The tape head comprises one or more modules, each module comprising a plurality of write heads aligned in a first row, a plurality of read heads aligned in a second row parallel to the first row, and at least four first servo heads aligned in the second row. Two or more first servo heads of the at least four first servo heads are configured to concurrently read first servo data from a first servo track. The controller is configured to concurrently process the first servo data, to compute the position of the tape head based on a known spacing between the at least two servo heads, and to dynamically adjust a position of the tape head based on the processed first servo data.”

The patent application was filed on 2022-02-24 (17/680068).

Tape drive having independently controlled tilting tandem tape heads
Western Digital Technologies, Inc., San Jose, CA, has been assigned a patent (11935563) developed by Noda, Junzo, Fujisawa, Japan, and Biskeborn, Robert G., Hollister, CA, for a “tape drive having independently controlled tilting tandem tape heads.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “The present disclosure generally relates to a tape drive. The tape drive comprises a first tape head and a second tape head linearly aligned with one another, where the first tape head and the second tape head are configured to concurrently operate. The first tape head and the second tape head each comprise a plurality of write transducers, a plurality of read transducers, and a plurality of servo transducers. The tape drive further comprises a first actuator coupled to the first tape head and a second actuator coupled to the second tape head. The first and second actuators are configured to independently tilt and move the first and second tape heads, respectively. Tilting and moving the first and second tape heads individually enables the tape drive to compensate for non-linear tape dimensional stability effects.”

The patent application was filed on 2022-03-10 (17/691904).
