An electric device includes flat acrylic lens, and a blue light emitting diode. The lens includes bottom face upon which light is incident from the diode; front face from which light is emergent; pair of side portions opposed to each other and inclined by a predetermined angle with respect to the front face and the bottom face; and back face arranged so that end portions of the pair of side can be connected, substantially making a right angle with the bottom face. The pair of side portions reflects the light sent from the bottom face in the direction of the front face. When the side portions are directed to the back face, an inclination angle of the side plate with respect to the bottom face portion gradually comes close to a right angle.

A method for managing a storage subsystem including a plurality of information recording media includes selecting at least one recording medium from the plurality of information recording media to perform a service to the selected recording medium. A locating device associated with the selected recording medium is activated to identify the location of the selected recording medium in the storage subsystem.

A disc drive apparatus according to the present invention has a tray formed of an optically transparent material and has disc receiving portions. The tray is movable in an ejection and a retraction direction with respect to a casing. A light source is mounted inside the tray at the ejection direction side thereof. The light source emits light toward the ejection direction of the tray to cause the light to propagate within the optically transparent material from the retraction direction side through the ejection direction side of the tray with respect to the disc receiving portion.

A reproducing apparatus, in which a disc insertion slot of car audio equipment can be opened and closed by a shutter member to prevent foreign substances, dust and the like from entering the disc insertion slot and in which a liquid crystal display portion is covered with the shutter member to turn off the illumination when driving at night. The reproducing apparatus includes a disc insertion slot in a front panel and a liquid crystal display portion below the disc insertion slot, in which a shutter board for opening and closing the disc insertion slot is provided on the front surface of the front panel and when the disc insertion slot is open, the liquid crystal display portion is covered with the shutter board to turn off the illumination of the liquid crystal display portion.

Glide heads for the detection of asperities on a storage disc have a thermal transducer oriented along the air bearing surface. The thermal transducer generally is in electrical contact with a circuit to measure the electrical resistance of the thermal transducer. Preferred methods of depositing the thermal transducer involve the deposition of the thermal transducer on the smooth surface of a wafer prior to the slicing of individual sliders.

A reproducer can enhance detection accuracy with respect to a rotational motion according to a scratch operation and properly change a reproducing speed of a recording medium. A turntable of a scratch operating part comprises a disk-shaped mounting plate, which is made from metal, fixed on the upper end of a bushing, a ring-shaped grooved member fixed on a marginal area of the under surface of the mounting plate with mounting bolts, and a marginal member fixed on an outer area of the ring-shaped grooved member. A disk has a disk surface on rollers provided on the top surface of the turntable and a ring-shaped detected part located around an outer circumference of the disk surface and projecting from the under surface of the disk. A light receiving element supplies a signal with a frequency proportional to a period in which a concave part and a convex part pass according to the rotational speed of the disk. Since the rotational speed of the disk operated by an operator can be directly detected, it is possible to enhance detection accuracy.

The occurrence frequency of read error occurring when the data on one disk is read by a read unit is compared with that when the data on another disk is read by the read unit and the evaluation result of relatively evaluating the disks is displayed on a display section as the ranking of the disks. Therefore, the user can easily and precisely determine the disk having a good affinity for the apparatus main unit.

In a removable disc drive apparatus having a plurality of switches for ejecting a disc, a user may operate erroneously. According to the present invention, a single eject switch (203) judges the state of the drive apparatus and specifies a normal mode or an emergency mode. Moreover, a power supply system is divided into two systems so that power is supplied from a connection point (P1) only to a portion required for eject utilizing an eject motor (209). Thus, it is possible to eject a disc only by using a small capacity of power.

The control section determines the rotational direction and the rotational speed of the operation discal unit based on the first pulse signal from the first optical sensor section. When determines that the operation discal unit starts rotating in the reference rotational direction after a pause of at least predetermined period of time, the control section controls the motor to rotate the discal unit temporarily at a speed higher than the reference rotational speed.

An image reproducing device has a post pin that is protrusively provided on a reproducing mechanism built-in box, a first post-pin locking mechanism that locks the post pin at the folding position of the reproducing mechanism built-in box by the folding/developing operation of the box, a second post-pin locking mechanism that responds to the operation of an image display unit to lock the post pin at the developing position of the reproducing mechanism built-in box, an image-display-unit locking mechanism in association with the folding operation of the image display unit to lock the image display unit at the storing position of the unit, and a common lock release actuating mechanism that simultaneously releases the lock of the first post-pin locking mechanism and the lock of the image-display-unit locking mechanism.
