Sony Group Assigned Three Patents

Cartridge including magnetic tape including magnetic layer including protrusions on surface
Sony Group Corporation, Tokyo, Japan, has been assigned a patent (12347457) developed by Yamaga; Minoru, and Iwahashi; Yuji, Tokyo, Japan, for a “cartridge including magnetic tape including magnetic layer including protrusions on surface thereof.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Provided is a cartridge capable of curbing charging of a magnetic tape even in a case where a drive gear is configured of an insulating resin. The cartridge includes a reel that has conductivity and includes a bottom wall, a magnetic tape that is wound around the reel, and a conductive member that is in contact with the reel, the conductive member having a reel gear on a lower surface of the bottom wall.”

The patent application was filed on 2022-03-31 (18/284223).

Servo pattern recording method, servo pattern recording apparatus, method of producing magnetic tape, magnetic tape, and tape cartridge
Sony Group Corporation, Tokyo, Japan, has been assigned a patent (12347470) developed by Morita; Hiroshi, and Anno; Kazuo, Tokyo, Japan, for “servo pattern recording method, servo pattern recording apparatus, method of producing magnetic tape, magnetic tape, and tape cartridge“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A servo pattern recording method according to an embodiment of the present technology is a method of recording a servo pattern in a plurality of servo bands arrayed at intervals in a width direction of a magnetic layer of a magnetic tape, including: causing the magnetic tape to travel with a predetermined tension; and recording a servo pattern in the plurality of servo bands at a second pitch narrower than a first pitch that is an arrangement interval of two servo read heads in a tape drive device that records data in the magnetic layer or reproduces data recorded in the magnetic layer.”

The patent application was filed on 2022-02-16 (18/281842).

Servo pattern recording apparatus, method of producing servo pattern recording method, and magnetic tape
Sony Group Corporation, Tokyo, Japan, has been assigned a patent (12340827) developed by Morita; Hiroshi, and Suzuki; Koji, Tokyo, Japan, for “servo pattern recording apparatus, method of producing a servo pattern recording method, and magnetic tape.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A servo pattern recording apparatus according to an embodiment of the present technology is an apparatus that records a plurality of servo patterns adjacent to each other in a tape width direction on a magnetic layer of a magnetic tape, including: a servo write head; and a temperature adjustment unit. The servo write head includes a plurality of recording units arranged corresponding to a plurality of servo bands of the magnetic layer on which the plurality of servo patterns is recorded. The temperature adjustment unit is configured to be capable of individually adjusting temperatures of the plurality of recording units.”
