摘要： A tape cassette which can be recorded and played back on both sides or in opposite directions has a lid having a pair of side arms pivotally mounted on lateral sides of a cassette casing for opening and closing a front opening in the cassette casing. The lid is normally held in a closed position by means of springs which normally urge pivot pins on the side arms toward a rear side of the cassette casing. The tape cassette also has protective plates integrally projecting in a forward direction from the lateral sides of the cassette casing in covering relation to the side arms, respectively. The protective plate protects the side arms against intentional or accidental engagement with a finger or a cassette recorder, thereby preventing the lid from being easily opened. The cassette recorder for use with the tape cassette includes abutments for engaging distal ends of the protective plates for accurately positioning the tape casette as inserted in the cassette recorder.

摘要： In a disk cartridge, a round portion with a circular arc shape whose center substantially coincides with that of a disk is formed at the forefront edge of the disk cartridge in the direction of insertion into a disk drive unit, and the remaining portion is a rectangular shape. The round portion preferably is formed so as to be decreased gradually in thickness toward its leading end. On the other hand, part of the components of the disk drive unit is arranged in an open space at corner portions at the forefront of the disk cartridge. A space in the disk drive unit thus can be utilized efficiently, whereby a small, thin disk drive unit having excellent operability and a disk cartridge permitting such a disk drive unit can be obtained.

摘要： A disk cartridge includes a substantially box-shaped outer case that has an opening on one end face, and an inner case that is housed in the outer case such that the inner case can be pulled out and has a concave portion for an optical disk to be placed therein. In an end portion on a side of the opening of each of an upper side plate and a lower side plate of the outer case, a substantially V-shaped cutout formed by a substantially circular arc and an inclined substantially straight line is formed. In the inner case, a substantially U-shaped cutout formed by a substantially circular arc and two inclined substantially straight lines is formed. The substantially straight line forming the substantially V-shaped cutout and the two substantially straight lines forming the substantially U-shaped cutout are virtually parallel to each other. The inner case further includes a cover that is opposed to a bottom face of the concave portion and fitted in the substantially V-shaped cutout when the inner case is housed in the outer case. Thus, a disk cartridge can be provided that allows a size reduction of a drive into which a single disk cartridge is loaded, and also can be used suitably in a changer drive.

摘要： A clamp plate retaining surface, a handling surface positioned outside the outer circumference of the clamp plate retaining surface, and an information surface outside the outer circumference of the handling surface are provided in a substrate. The handling surface is formed to be a slope with its outer circumferential side being inclined downward with respect to the information surface. The resin forming the inner circumferential side end of the handling surface is melted and deformed to form a projection part, so that a clamp plate can be retained. Since the top part of the slope is deformed, a large projection part can be formed. As a result, a thin small-diameter optical disk and substrate can be obtained.
