A shutter operating member is mounted on the cartridge casing, and is operable from the outside of the cartridge casing. When the insertion openings are closed, the shutter operating member is engaged with the head shutter and the spindle shutter to hold them against their opening movements, and when the insertion openings are to be opened, the shutter operating member is disengaged from the spindle shutter, and also acts on the head shutter to open the head shutter. A shutter opening-closing mechanism is provided in a disk drive unit, and includes a first shutter opening member for operating the shutter operating member, and a second shutter opening member for moving the head shutter from its half-opened position to its fully-opened position.

摘要： A write-once optical information recording medium is provided that is capable of realizing a high transfer rate and a method of recording and reproducing information on and from the optical information recording medium. The optical information recording medium is constructed by stacking a reflective layer 12, a first dielectric layer 13, a recording layer 14, a write-protect layer 15, a second dielectric layer 16 and a transparent cover layer 17 on a polycarbonate substrate 11. The recording layer 14 is made of a phase-change material, and the cover layer 17 is made of UV curing resin. The recording layer 14 is irradiated with a laser beam with a wavelength of 500 nm or less to change from a crystalline phase to an amorphous phase. The write-protect layer 15 prevents the recording layer 14 from changing back to the crystalline phase from the amorphous phase, formed by the phase change.

摘要： A thin-film magnetic head has a first ferrite block on which a plurality of transducing elements are aligned on a predetermined surface, and a second ferrite block bonded to the first ferrite block, and has multi-track capabilities in accordance with the transducing elements. Eithr bonding surface of the first and second ferrite block is formed with an insulating film layer, the entire bonding surface is coated with an adhesive or formed with a plurality of recesses to be externally filled with the adhesive, and the adhesive is filled in gaps defined by the recesses and the surface of the opposed ferrite block. Thus, since the bonding portions of the first and second ferrite blocks are distributed over a wide region, the bonding strength can be largely increased, the transducing gap lengths are uniformly maintained, and the transducing element characteristic is not affected by the aging of the adhesive thereby improving the reliability of the magnetic head.
