摘要： An optical disk drive of the type having a fixed optical unit having a light transmitting hole from which a laser beam is emitted, and a movable head having a light receiving hole from which the laser beam is received, wherein the respective outer edges of the light emitting and receiving holes are surrounded by a pair of annular projections. The annular projections are engageable with each other to provide a seal therebetween when the head is displaced toward the fixed optical unit. The annular projections are preferably made of a cushioning material in which instance they also serve as a cushioning or shock-absorbing member.

摘要： A shutter opening and device includes movable components such as a lever, an actuating pin and a spring all disposed in a guide channel of a cartridge holder into which a disk cartridge is inserted. The device of this construction is low in profile and compact in size and makes it possible to reduce the overall size of a disk drive in which the device is incorporated. With the combination of a straight guide groove and an oblique guide groove formed in the cartridge holder, the actuating pin is movable along a substantially straight path. This enables the user to insert the disk cartridge into the cartridge holder smoothly with a small muscular effort.

摘要： According to the present invention, a stepping motor driving apparatus having a rotor and a stator in n (an integer equal to or larger than 2) phases for moving a moving body is provided. The stepping motor driving apparatus includes a driver for selectively supplying to the stator a first current pattern for rotating the rotor at a first pitch and a second current pattern for rotating the rotor at a second pitch different from the first pitch based on a drive switching signal. The driver switches the first current pattern and the second current pattern at a point where a torque generated by the first current pattern is equal to a torque generated by the second current pattern and supplies the first current pattern or the second current pattern to the stator.
