20220208222 | MAGNETIC RECORDING MEDIUM, MAGNETIC RECORDING/REPRODUCING DEVICE, AND MAGNETIC RECORDING MEDIUM CARTRIDGE - A magnetic recording medium that can exhibit good traveling performance during use is provided. This magnetic recording medium is a tape-shaped magnetic recording medium, and includes a substrate including a polyester as a main component, a base layer disposed on the substrate, a magnetic layer disposed on the base layer, and a back layer disposed on a side of the substrate opposite to the base layer. A surface of the back layer opposite to the substrate has a kurtosis of 2.0 or more. On a surface of the magnetic layer, recesses having a depth of 20% or more of the average thickness of the magnetic layer are formed at a ratio of 10 or more and 200 or less per 1600 μm | 2022-06-30 |
20220208223 | FERROELECTRIC RECORDING MEDIUM AND FERROELECTRIC STORAGE APPARATUS - A ferroelectric recording medium includes an electrode layer, a ferroelectric recording layer, and a protection layer formed in this order on a substrate, wherein the ferroelectric recording layer includes a ferroelectric layer, and a lattice constant of a material constituting the ferroelectric layer and a lattice constant of a material constituting the electrode layer or the substrate are lattice-matched within a range of ±10%. | 2022-06-30 |
20220208224 | TAPE DRIVE WITH HEAD-GIMBAL ASSEMBLY AND CONTACT PLATE - The present disclosure generally relates to a tape embedded drive having a head-gimbal assembly (HGA) and a contact plate. By using a support structure or contact plate beneath the tape, read and write heads can be designed to be narrower than the tape. The support structure or contact plate can stretch or relax the tape so that the spacing between servo tracks on the tape corresponds to the servo to servo spacing on the head. HGAs, which are narrower than the tape, can fly over the tape and read data from and write data to the tape. The HGA can have a single head or multiple heads. Additionally, multiple independent head assemblies can also be used for reading from and writing to the same tape. | 2022-06-30 |
20220208225 | MAGNETIC DISK DEVICE AND DEMODULATION METHOD FOR SERVO DATA - According to one embodiment, a magnetic disk device includes a disk having first servo data including a first preamble, a first servo mark, a first gray code, first burst data, and second burst data written after the first burst data, a head including a write head that writes data to the disk and a first read head and a second read head that read data from the disk, and a controller that reads the second burst data using the first read head and the second read head and calculates a servo demodulation position when the first servo data is servo-read without reading the first burst data in a short servo mode in which the first preamble, the first servo mark, and the first gray code are not read. | 2022-06-30 |
20220208226 | MAGNETIC TAPE CARTRIDGE AND MAGNETIC TAPE DEVICE - The magnetic tape cartridge includes a magnetic tape, and a cartridge reel, in which, in the magnetic tape, a minimum winding deviation occurrence load measured after the magnetic tape is rewound around the cartridge reel by applying a tension of 0.20 N in a longitudinal direction of the magnetic tape is 200 N or less. | 2022-06-30 |
