    摘要: A magnetic recording medium in which a silicon nitride film is formed on a magnetic recording layer having an axis of easy magnetization in the direction essentially perpendicular to its own layer surface. The magnetic recording layer is a metallic magnetic film such as a Co-Cr containing alloy. The silicon nitride film is preferably in a state in which the number of nitrogen atoms is less than four thirds of the number of silicon atoms. A lubricant layer such as a layer of fluorocarbon can be formed on the silicon nitride film.

    摘要: A perpendicular magnetic floppy disk has a base layer on each side of which a recording layer is formed having an axis of easy magnetization in a direction perpendicular to its surface. A multilayered protective layer structure is provided on the recording layer. The protective layer structure includes double-stacked non-magnetic thin-film layer structures made of an Si-N-O-based film and silicon oxide film, respectively. The total thickness of the multilayered protective layer structure is smaller than 40 nanometers, which is thin enough to maximize an efficiency in perpendicular magnetic recording of data signal.

    摘要: A magnetic recording medium obtained by forming a Si-N-O system film on a magnetic recording layer with perpendicular axis of easy magnetization. The magnetic recording layer is a metallic magnetic film such as Co-Cr system alloy film. The oxygen content in the Si-N-O system film is selected preferably to show a maximum absorption of infrared radiation in the range above 830 cm.sup.-1 and below 1100 cm.sup.-1 of 1/.lambda. (.lambda. is the wavelength of the infrared radiation). Through formation of the Si-N-O system film, the magnetic recording medium can satisfy simultaneously both of the durability and the perpendicular magnetic recording characteristics.

    摘要: A disk device and microphone are arranged in a device main body. The case of the disk device includes a first shell having a bottom, and a second shell having a top cover. A disk-shaped recording medium is contained in the case. The microphone is positioned closer to the top cover of the disk device than to the bottom of the disk device in the thickness direction of the device main body. Assuming that θ represents the angle between straight line connecting the disk device to the microphone by the most direct way, and a plane parallel to a surface of the top cover of the disk device, the disk device and microphone arranged to satisfy the following relationship with respect to the maximum deformation angle α of the top cover of the disk device in a lowest-order vibration mode: 0≦θ

    摘要: In an optical disc recording and reproducing apparatus, when a time shift determining unit determines that a time shift reproduction is currently performed, a reservation determining unit determines whether or not there is a timer reservation in the next place. When it is determined that there is the timer reservation and a pre-time determining unit determines that the timer reservation is performed a prescribed time before a reserved time, a first reservation performing unit performs an operation of a record by the timer reservation. Then, after the recording by the timer reservation is finished, a time shift reproducing unit continuously performs the time shift reproduction without turning off a power. After the time shift reproduction is continuously performed, when there is a timer reservation, a second reservation performing unit performs recording by the timer reservation.
