摘要： An optical disc apparatus includes position restricting component for restricting the position of a unit mechanism portion in a disc plane direction when the unit mechanism portion is in a raised state. The position restricting component includes a first portion that restricts the position of a base of the unit mechanism portion when the base is at a height position for write or read of information to or from an optical disc and a second portion that cancels the position restriction on the base of the unit mechanism portion in the disc plane direction or makes the position restriction easier than in the first portion when the base is at a height position corresponding to a chucked portion of the optical disc onto the turntable. At the height position where the optical disc is chucked the position restricting component makes the turntable displaceable in the disc plane direction so that the axis of the turntable becomes nearly coincident with the center of a center hole formed in the optical disc.

摘要： An optical disc apparatus has a bottom cover member provided with an opening. A peripheral part of a unit mechanism deck member serving as a support member in a functional unit mechanism or a motor base holding a spindle motor and fixed to the unit mechanism deck member is projected outside through the opening when the optical disc apparatus is set in a loaded state to space a part of the functional unit mechanism projecting in a direction opposite to a direction in which the peripheral part of the unit mechanism deck member or the motor base is projected outside from a surface of the optical disc.

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.
