FujiFilm Assigned Four Patents

Recording tape cartridge and barcode label reissuing
FujiFilm Corp., Tokyo, Japan, has been assigned a patent (11,080,499) developed by Osako, Ryosuke, and Sumiya, Yosuke, Kanagawa, Japan, for “recording tape cartridge and barcode label reissuing method.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”A recording tape cartridge includes a case that accommodates a reel around which a recording tape is wound and a label that is attached to a label surface formed at a wall surface of the case. The wall surface is located at a side opposite to a direction in which the case is loaded into a drive device. The label includes a first label layer that is attached to the label surface and on which individual identification information is displayed in a two-dimensional code, and a second label layer attached to the first label layer with a peelable bonding force, the second label layer being capable of covering and concealing the two-dimensional code, and the individual identification information being displayed in a barcode on the second label layer. The two-dimensional code is displayed at a central part in a longitudinal direction of the label.”

The patent application was filed on April 8, 2020 (16/842,774).

Recording tape cartridge, barcode printing and manufacturing recording tape cartridge with barcode
FujiFilm Corp., Tokyo, Japan, has been assigned a patent (11,080,494) developed by Osako, Ryosuke, and Sumiya, Yosuke, Kanagawa, Japan, for “recording tape cartridge, barcode printing system, barcode printing method, and method of manufacturing recording tape cartridge with barcode.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”A recording tape cartridge includes a case that is formed by a first half in which a first peripheral wall is erected around a top plate and a second half in which a second peripheral wall is erected around a bottom plate being joined to each other in a state where the first peripheral wall and the second peripheral wall are butted against each other and that stores a reel on which the recording tape is wound, and a label surface formed by a first half label surface of the first peripheral wall and a second half label surface of the second peripheral wall on a side opposite to a loading direction of the case to a drive device, and a one-dimensional barcode on which individual identification information is recorded is printed only on the second half label surface.”

The patent application was filed on February 14, 2020 (16/790,757).

Magnetic tape, tape cartridge, and apparatus
FujiFilm Corp., Tokyo, Japan, has been assigned a patent (11,056,141) developed by Kasada, Norihito, Ozawa, Eiki, and Musha, Atsushi, Minami-ashigara, 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 including ferromagnetic powder and a binding agent, in which the magnetic layer has a timing-based servo pattern, an edge shape of the timing-based servo pattern, specified by magnetic force microscopy is a shape in which a difference (L.sub.99.9-L.sub.0.1) between a value L.sub.99.9 of a cumulative distribution function of 99.9% and a value L.sub.0.1 of a cumulative distribution function of 0.1% in a position deviation width from an ideal shape of the magnetic tape in a longitudinal direction is 180 nm or less, and an isoelectric point of a surface zeta potential of the magnetic layer is 3.8 or less.”

The patent application was filed on January 30, 2020 (16/777,312).

Magnetic tape recording device having dual reading transducers
FujiFilm Corp., Tokyo, Japan, has been assigned a patent (11,017,805) developed by Kaneko, Tetsuya, and Musha, Atsushi, Kanagawa, Japan, for a “magnetic tape recording device having dual reading transducers.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”A magnetic tape reading apparatus comprises an acquisition unit that acquires information on linearity of a servo pattern to be recorded on a servo band of a magnetic tape, a reading element unit in which at least two reading elements each of which reads data from a specific track region included in the magnetic tape are disposed, a servo reading element that reads the servo pattern, a control unit that performs control of positioning the reading element unit, a derivation unit that derives a deviation amount, and an extraction unit that extracts data recorded on the reading target track by performing a waveform equalization process on each reading result for the reading elements in accordance with the deviation amount.”

The patent application was filed on February 20, 2020 (16/795,800).
