摘要： A scanning optical system deflects a light beam by a reflection surface of a polygon mirror toward an object surface through an image forming optical system so that the light beam scans on the object surface to form an image thereon. A light shielding member is disposed between the polygon mirror and the image forming optical system. The shielding member is an opaque plate disposed perpendicular to the optical axis of the image forming optical system. The light shielding member prevents a ghost light that is reflected by another reflection surface of the polygon mirror located adjacent to the reflection surface deflecting the light beam from entering the image forming optical system and impinging onto the object surface.

摘要： A disk cartridge loading system for a disk drive. The loading system includes a disk cartridge holder, a drawing mechanism, a draw-in sensor, a loading sensor, and a controller. The drawing mechanism engages a partially inserted disk cartridge to fully draw the disk cartridge into the disk drive, so that the disk cartridge is accommodated in a disk cartridge holder. A holder moving mechanism moves the disk cartridge holder to a loading position, so that at least one of a data reading operation and a data writing operation can be performed. A draw-in sensor is provided to detect the partial insertion of the disk cartridge, while a loading sensor detects when the disk cartridge is located at the loading position. A control unit controls the drawing mechanism and the holder moving mechanism, based on a first signal produced by the draw-in sensor and a second signal produced by the loading sensor.

摘要： A shutter opening mechanism in a data recording/reproducing device engages a shutter of a disk cartridge which is being inserted into the data recording/reproducing device to open the shutter as the disk cartridge is inserted. The opening mechanism includes a pin and a roller provided at an end of an arm. The pin is formed as a hollow cylinder that includes a slit along a length of the pin, and the roller is provided with a hole. During assembly, the pin is compressed to narrow the slit for insertion into the hole so that the roller is resiliently secured to the pin. Over time, the pin expands and ensures that the roller remains secured to the pin.

摘要： A magneto-optical disk drive system, utilizing a magnetic field modulation recording method, has a disk cartridge for housing a magneto-optical disk therein and insertable into a system housing and a magnetic head in the system housing for writing information on the magneto-optical disk held in the disk cartridge. The disk cartridge is guided by cam grooves and cam pins for movement between a first unloading position and a first loading position when inserted in the system housing. The magnetic head is guided by cam grooves and cam pins for movement between a second unloading position remote from the disk cartridge and a second loading position close to the disk cartridge. The magnetic head is normally urged to move from the second loading position toward the second unloading position under the bias of a tension spring. A lock arm is attracted by an electromagnet to lock the magnetic head in the second loading position when the main power supply of the magneto-optical disk drive system is turned on. When the electromagnet is de-energized, the lock arm is released, unlocking the magnetic head to move from the second loading position toward the second unloading position toward the second unloading position under the bias of the tension spring.
