摘要： In a disc drive for achieving cooling of an electronic part therein, as well as, suppressing transmission of noises generated from a disc clamper, etc., a channel member 18 for introducing an outside air into an inside is disposed between a supporting member 15 and a top-cover 10, within an inside thereof is formed a vortex-like channel, extending from a center to an outer periphery thereof. At the center of the channel member 18 is formed an opening 19 for introducing the outside air into the inside of the disc drive, and on the top-cover 10 are provided plural numbers of openings 20 for taking the outside air into the channel member 18. When an optical disc 6 rotates, pressure generated on an upper surface thereof comes to be negative to the outside air, then the outside air is taken from the openings 20, through the vortex-like channel of the channel member 18 and the opening 19, into the inside of the drive, so as to pass through electronic parts, such as, an optical pickup, etc., thereby cooling them. Noises generated from the disc clamper 17 are attenuated within the vortex-like channel of a long route, which is formed within the channel member 18.

摘要： A flexible printed-wiring circuit board that connects a signal-processing circuit board and a pickup is prevented from coming into contact with the bottom (or the like) of a tray and thus becoming damaged. The flexible printed-wiring circuit board (FPC board) is disposed in a U-shaped folded state in a space sandwiched between a surface along which the tray moves, and a surface on which the signal-processing circuit board is mounted. An extension portion that restricts deformation of the FPC board toward the tray is provided at a connecting end of the pickup. Length D of the extension portion is set such that length S of the FPC board from a front end of the extension portion to a fold-back position of the FPC board is equal to or less than a required value.
