Sony Corporation, Tokyo, Japan, has been assigned a patent (10,984,819) developed by Adachi, Naohiro, Tokyo, Japan, Nakashio, Eiji, Anno, Kazuo, Tochikubo, Shinya, Yamaga, Minoru, Iwama, Takanobu, Miyagi, Japan, and Abe, Masayoshi, Tokyo, Japan, for a “magnetic tape recording device including cartridge memory having a plurality of memory banks.“
The abstract of the patent published by the U.S. Patent and Trademark Office states: ”A cartridge memory used for a tape cartridge includes: a communication unit that communicates with a recording and reproducing device using a wireless communication method defined by an ISO 14443-2 standard which is a wireless communication standard, a non-volatile memory with a storage capacity exceeding 16 KB, and a control unit that writes or reads data to or from the non-volatile memory on a word-by-word basis (2 bytes at a time) or on a block-by-block basis (32 bytes at a time). The non-volatile memory includes a plurality of memory banks each having a storage capacity of 128 KB or less. The control unit writes or reads data defined by a magnetic tape standard to or from one or two or more first memory banks among the plurality of the memory banks, and writes or reads additional data to or from one or two or more second memory banks other than the first memory bank.”
The patent application was filed on February 8, 2019 (Appl. No.16/620,756).
Magnetic recording medium having dimensional variation and cartridge
Sony Corporation, Tokyo, Japan, has been assigned a patent (10,978,104) developed by Yamaga, Minoru, and Sekiguchi, Noboru, Miyagi, Japan, for a “magnetic recording medium having a dimensional variation and cartridge.“
The abstract of the patent published by the U.S. Patent and Trademark Office states: ”A tape-type magnetic recording medium, includes a substrate; and a magnetic layer provided on the substrate. The magnetic recording medium is configured such that (1) (w.sub.max-w.sub.min)/w.sub.min.ltoreq.400 [ppm] where w.sub.max and w.sub.min are respectively maximum and minimum of average values of width of the magnetic recording medium measured under four environments whose temperature and relative humidity are (10.degree. C., 10%), (10.degree. C., 80%), (29.degree. C., 80%), and (45.degree. C., 10%), respectively, and the magnetic layer has a squareness ratio of 65% or more in the vertical direction, and (2) 4.4.ltoreq.T.sub.B/(T.sub.A-T.sub.B) where T.sub.A is an average thickness of the magnetic recording medium and T.sub.B is an average thickness of the substrate.”
The patent application was filed on June 28, 2019 (Appl. No.16/456,209).
