    摘要： The magnetic recording medium includes: an underlayer constituted of at least a substrate and a nonmagnetic metal element; and an amorphous magnetic layer, made of amorphous magnetic material, which magnetically records information, wherein the amorphous magnetic layer has bumps on a surface thereof or the magnetic recording medium has bumps on a surface thereof (surface of a lubricating layer) so that density of the bumps is not less than 400 bumps/nullm2 or so that height of the bumps is not less than 2% with respect to an average layer thickness of the amorphous magnetic layer. Thus, magnetic wall movement of the amorphous magnetic layer is effectively suppressed, so that it is possible to stably form a recording bit. Therefore, even in a case of performing high-density recording by forming a minute recording bit, it is possible to record information with sufficient signal quality. Further, a magnetic recording device causes the magnetic recording medium to record information by locally heating the amorphous magnetic layer and by applying a magnetic field to at least one part of a heated region.

    摘要： A data library supporting a plurality of data cartridges, at least one filter cartridge, and a picker/placer mechanism that is capable of manipulating both types of cartridges. The filter cartridge prevents airborne particulates from contaminating the data library. The cartridge design allows the picker/placer to be used to insert or remove a filter for cleaning or replacement, thereby obviating the need for shutting down the library for filter maintenance.

    摘要： An information disk has a disk structure with a metalized data storage area. A radio frequency identification processor that is activatable by light, such as laser light, is coupled to the disk structure to prevent copying of copyrighted or otherwise secured data, and to prevent unauthorized use of the information disk. The processor may be positioned at a variety of locations on the information disk, including in the inner non-conductive area, and the outer non-conductive ring, as well as within the metalized data storage area. A process for enabling an information disk with an RFID processor includes providing a disk structure having a metalized data storage area, and positioning a short wavelength electromagnetic light activated radio frequency identification processor on the disk structure.

    摘要： An optical disk includes a reflective layer, a recording layer, an optical-transparent bonding layer and an optical transparent sheet laminated on a substrate in this order. The total thickness of the optical-transparent bonding layer and the optical transparent sheet is 0.1 mm. The peak-to-peak height of wrinkles formed on the sheet is 2.5 nullm or lower. The optical disk is produced as follows: A first ultraviolet ray is radiated to an optical transparent sheet at a first energy level in the range from 500 mJ/cm2 to 3000 mJ/cm2, a wavelength of the first ultraviolet ray being in the range from 250 nm to 300 nm. Prepared next is a substrate laminated on which are a reflective layer and a recording layer in this order. Ultraviolet hardened resin is applied on the recording layer to form an optical-transparent bonding layer thereon. An optical transparent sheet is provided on the optical-transparent bonding layer. A second ultraviolet ray is radiated to the optical transparent sheet at a second energy level the same as or lower than the first energy level, to harden the optical-transparent bonding layer, thus the optical transparent sheet being bonded on the substrate via the optical-transparent bonding layer.
