摘要： There is provided a disc drive by which the fluid loss of a disc is reduced and the electric power consumption of a spindle motor can be decreased. In the disc drive according to the present invention, a rotation load reducing member is provided between a top cover and the disc. The rotation load reducing member is movably supported by a clearance adjustment member. While the disc is rotating, the rotation load reducing member is moved in the direction approaching the disc. Thereby, the thickness of an air layer on the upper surface of the disc is decreased.

摘要： An optical disc drive is fitted with a pickup, a non-contacting cooling plate, and a resinous movable spacer. The cooling plate adjacently faces and is fixed to the under, right, or left side of the pickup. The movable spacer is fitted to one of the facing sides of the pickup and cooling plate and prevents direct contact between the pickup and the plate. This drive structure prevents pickup movement interference due to collision between the pickup and the cooling plate, contamination production, needless electric conduction, etc., so that the clearance between the facing sides of the metallic pickup and metallic non-contacting cooling plate is narrow. The narrow clearance results in an improved heat conduction and radiation characteristic, improving the cooling of the whole pickup.

摘要： A magnetic recording and reproducing apparatus has main and sub chassis relatively movable between a first position in which a tape cassette is allowed to be mounted on and demounted from the reel bases and a second position in which magnetic tape extracted from the tape cassette is wound on the head assembly for recording or reproduction of electric signals. The apparatus has a braking mechanism designed for producing a braking effect on at least one of the reel bases when the sub chassis is in the first position. When the sub chassis is in the second position, the braking mechanism is engaged with a brake actuating mechanism on the main chassis so as to selectively brake the reel base in accordance with the state of the brake actuating mechanism operative in response to a manual input.

摘要： A cassette loading device comprises a motor rotatable in a normal direction and in a reverse direction, a driving mechanism for transmitting a power of the motor to a cassette holder and moving the cassette holder, and elastic member mounted on the driving mechanism for generating an elastic force against a depression of a tape cassette when the tape cassette is depressed from an initial position to a cassette-in position. A position detecting device detects that the cassette holder reaches a predetermined position in its moving path and generates a signal, with an initial position detecting device detecting an initial position of the elastic member upon initializing generating a signal. An eject signal generating device generates a signal commanding a cassette unloading, and a micro-processor controls the motor in response to output signals from the position detecting device, the initial position detecting device and the eject signal generating device. The tape cassette is forcibly unloaded irrespective of the elastic force of the elastic member.

摘要： To prevent deformation of a chassis due to an impact force in an optical disc apparatus, there is provided a tray for inserting/ejecting an optical disc into/from an apparatus body, with the chassis connected thereto through vibration proof materials in plural portions in a surface opposite a disc placing surface. The tray has projecting portions projecting in a chassis direction in positions facing the chassis in peripheral portions of the plural connecting portions. The projecting portion is located at a position higher than a tray plane with which the vibration proof material comes into contact, and lower than the surface of a chassis facing the tray. When the vibration proof material is compressed and deformed due to the impact force, the projecting portion comes into contact with the chassis facing surface, to reduce the amount of deformation of the vibration proof material and thereby prevent deformation of the chassis.
