FujiFilm Assigned Two Patents

Magnetic tape device
FujiFilm Corporation, Minato-Ku, Tokyo, Japan, has been assigned a patent (10,325,623) developed by Kasada, Norihito, Ozawa, Eiki, and Kaneko, Tetsuya, Minami-ashigara, Japan, for “magnetic tape device and magnetic reproducing method.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”The magnetic tape device includes: a magnetic tape, and a reproducing head, in which a magnetic tape transportation speed of the magnetic tape device is equal to or lower than 18 m/sec, the reproducing head is a magnetic head including a tunnel magnetoresistance effect type element as a reproducing element, the magnetic tape includes a non-magnetic support, and a magnetic layer including ferromagnetic powder and a binding agent on the non-magnetic support, and a coefficient of friction measured regarding a base portion of a surface of the magnetic layer is equal to or smaller than 0.30.”

The patent application was filed on December 26, 2017 (15/854,409).

Magnetic tape device and head tracking servo
FujiFilm Corporation, Minato-Ku, Tokyo, Japan, has been assigned a patent (10,325,620) developed by Kaneko, Tetsuya, Kasada, Norihito, and Ozawa, Eiki, Minami-ashigara, Japan , for “magnetic tape device and head tracking servo method.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”The magnetic tape device includes: a magnetic tape, and a servo head, in which a magnetic tape transportation speed of the magnetic tape device is equal to or lower than 18 m/sec, the servo head is a magnetic head including a tunnel magnetoresistance effect type element as a servo pattern reading element, the magnetic tape includes a non-magnetic support, and a magnetic layer including ferromagnetic powder and a binding agent on the non-magnetic support, the magnetic layer includes a servo pattern, and a coefficient of friction measured regarding a base portion of a surface of the magnetic layer is equal to or smaller than 0.30.”
