FujiFilm Assigned Six Patents

Magnetic tape cartridge, drive, system, and method of operating magnetic tape drive
FujiFilm Corporation, Tokyo, Japan, has been assigned a patent (12272390) developed by Nakao; Toru, Kasada; Norihito, Kaneko; Tetsuya, and Musha; Atsushi, Kanagawa, Japan, for “magnetic tape cartridge, magnetic tape drive, magnetic tape system, and method of operating magnetic tape drive.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A magnetic tape cartridge includes a case in which a magnetic tape is accommodated and a storage medium provided in the case. At least one of reading or writing of data is performed by a plurality of magnetic elements, which are linearly disposed, with respect to the magnetic tape pulled out from the case. A disposition direction of the plurality of magnetic elements is tilted toward an entire length direction side of the magnetic tape with respect to a width direction of the magnetic tape. The storage medium stores tilt feature information indicating a feature of tilt of the disposition direction with respect to the width direction.”

The patent application was filed on 2023-02-17 (18/170683).

Magnetic tape cartridges package
FujiFilm Corporation, Tokyo, Japan, has been assigned a patent (12272378) developed by Sumiya; Yosuke, Kanagawa, Japan, for a “magnetic tape cartridges package.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A package includes a plurality of accommodation regions where a plurality of holders are accommodated in such a manner that the plurality of holders are able to be put in and out, and a partition structure that divides the plurality of accommodation regions. Each holder holds a plurality of magnetic tape cartridges in such a manner that the plurality of magnetic tape cartridges are able to be put in and out of the holder. In a state in which the holder is accommodated in the accommodation region, a height of the partition structure is higher than a height of the holder.”

The patent application was filed on 2023-07-13 (18/352221).

Magnetic tape, cartridge, and magnetic tape apparatus
FujiFilm Corporation, Tokyo, Japan, has been assigned a patent (12249360) developed by Kasada; Norihito, Minamiashigara, Japan, for “magnetic tape, magnetic tape cartridge, and magnetic tape apparatus.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “The magnetic tape includes a non-magnetic support, and a magnetic layer containing a ferromagnetic powder. The ferromagnetic powder is a hexagonal ferrite powder, tilt cos θ of the hexagonal ferrite powder with respect to a surface of the magnetic layer, which is acquired by cross-sectional observation performed using a scanning transmission electron microscope, is 0.85 or more and 1.00 or less, and standard deviation σ of the cos θ in a width direction of the surface of the magnetic layer is 0.03 or less.”

The patent application was filed on 2023-12-13 (18/538907).

Magnetic tape cartridge, drive, memory, tape, system, and operation method of magnetic tape drive
FujiFilm Corporation, Tokyo, Japan, has been assigned a patent (12243568) developed by Yamasaki; Nagisa, Nakao; Toru, Musha; Atsushi, and Takishima; Kento, Kanagawa, Japan, for “magnetic tape cartridge, magnetic tape drive, memory, magnetic tape, magnetic tape system, and operation method of magnetic tape drive.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A magnetic tape cartridge includes a magnetic tape, and a storage medium in which information on the magnetic tape is stored. The magnetic tape has a recording surface. Data is recorded in the recording surface by a magnetic head in a state in which the magnetic tape is made to travel. The magnetic head is disposed at an inclined posture with respect to a width direction of the magnetic tape along the recording surface. Angle adjustment information obtained before the data is recorded in the recording surface is stored in the storage medium. The angle adjustment information is information for adjusting an angle at which the magnetic head is inclined with respect to the width direction along the recording surface.”

The patent application was filed on 2022-12-22 (18/145119).

Magnetic tape cartridge, drive, tape, system, and operation method of magnetic tape drive
FujiFilm Corporation, Tokyo, Japan, has been assigned a patent (12223987) developed by Yamasaki; Nagisa, Nakao; Toru, Musha; Atsushi, and Takishima; Kento, Kanagawa, Japan, for “magnetic tape cartridge, magnetic tape drive, memory, magnetic tape, magnetic tape system, and operation method of magnetic tape drive.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A magnetic tape cartridge includes a magnetic tape, and a storage medium in which information on the magnetic tape is stored. The magnetic tape has a recording surface. Data is recorded in the recording surface by a magnetic head in a state in which the magnetic tape is made to travel. The magnetic head is disposed at an inclined posture with respect to a width direction of the magnetic tape along the recording surface. Angle adjustment information obtained at a data recording timing which is a timing at which the data is recorded in the recording surface is stored in the storage medium. The angle adjustment information is information for adjusting an angle at which the magnetic head is inclined with respect to the width direction along the recording surface.”

The patent application was filed on 2022-12-22 (18/145257).

Magnetic tape cartridge and magnetic recording and reproducing device
FujiFilm Corporation, Tokyo, Japan, has been assigned a patent (12217777) developed by Kasada; Norihito, and Kaneko; Yusuke, Minamiashigara, Japan, for “magnetic tape cartridge and magnetic recording and reproducing device.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “In the magnetic tape, a magnetic tape deformation amount after storage for 3 months each in a predetermined environment is 0.50 μm or less, a rate of a change in the magnetic tape deformation amount with respect to a change in relative humidity is 0.0001 μm/% to 0.0500 μm/%, and a rate of a change in magnetic tape deformation amount with respect to a change in temperature is 0.0010 μm/° C. to 0.1000 μm/° C.”
