摘要： In a rotary head drum of a recording/reproduction apparatus, for smoothly holding a magnetic tape over a guide step provided on a lower drum to guide the magnetic tape, part of a chamfer formed in the guide step is formed as a large chamfer in which a chamfered amount is larger than that of the remaining part of the chamfer. With the provision of the large chamfer, even if the lower edge of the magnetic tape deviates from the guide step when the tape is wound over or unwound from the drum, damages of the magnetic tape can be prevented. Therefore, the position and attitude control of tape withdrawing members can be greatly simplified and the magnetic tape can always run stably while being restricted in its position by the guide step. In the process of machining a tape running surface on the drum, by increasing the feed distance of a blade in the part of the chamfer where the large chamfer is to be formed by chamfering the guide step with a large chamfered amount, in comparison with the feed distance set in the remaining part of the chamfer, the large chamfer and the small chamfer can be both machined at the same time, resulting in simplified machining steps.

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.

摘要： In an optical disk drive device, in order to reduce structural vibration noise and aerodynamic sound during high-speed revolution, a recess is formed at the deeper end. This recess is in a position axially symmetric to a hole for the movement of an optical head with respect to the axis of a spindle motor, and its size is substantially equal to that of the movement hole. This recess serves to suppress the vibration mode of a disk tray and the air flow between the disk and the disk tray. Noise is reduced even when the disk is turning at high speed.
