摘要： A disk drive device has a configuration in which one of stepped parts defined by a circular recess for guiding a disc, formed in a disc tray is substantially flush with the bottom surface of the circular recess even in an area beyond the outer peripheral part of a disc so that no air cavity part facing the outer peripheral side surface of the disc is induced around the disc. Thereby, it is possible to aim at lowering cavity noise caused by the air cavity during high speed rotation and fluid noise caused by turbulence.

摘要： In an optical disc drive, a degradation of traveling performance of an optical pickup under hard acceleration or hard deceleration in a random access operation or the like results in a degradation of recording/reproducing performance. Groove structure is provided between two gears of a guide feed provided in an optical pickup, and the groove forms bending structure. Thus, the engagement state between a screw gear and the gears of the guide feed is stabilized. This makes it possible to prevent tooth jumping and step-out from occurring in the gears during the traveling of the optical pickup, achieving stable traveling. In consequence, the recoding/reproducing performance of the optical disc drive can be improved.

摘要： An optical disc drive with low vibration and low noise without risk of damage to components and injury caused by ejection of the disc tray with the rotating optical disc from a housing is provided by simple structure. In a disc-tray scheme of the optical disc drive, a brake member attached to the inside of the housing is placed to be in contact with the optical disc sliding thereon when the disc tray is in a predetermined position except the disc recording/reproducing position and the disc loading/unloading position, and to be connected to the disc tray when the disc tray is in the disc recording/reproducing position.
