Abstract: Disclosed is a disk clamper for cooperating with a disk table to chuck a disk-type recording medium, comprising: a support section disposed in an opposing relationship to the disk table; and a stabilizer supported on the support section for movement toward and away from the disk table; wherein, when the disk-type recording medium is chucked, the stabilizer is attracted to the disk table with the disk-type recording medium interposed therebetween, but when the disk-type recording medium is not chucked, the stabilizer is attracted to the support section. Accordingly, chucking operation in an assured manner can be realized.

Abstract: An audio signal processing apparatus including a plurality of jack units each of which has at least an audio signal contact piece and a control signal contact piece. A control circuit judges a kind of an audio appliance connected to each of the plurality of jack units based on a control signal obtained at the control signal contact piece, and when a function change-over command to select any one of the audio appliances is supplied, a function selecting circuit selects one of the jack units to which the audio appliance is connected. An audio appliance can be connected to any of the plurality of jack units.

Abstract: An optical disc reproducing apparatus and an optical disc reproducing method are adapted to use, as a medium for reproduction, an optical disc on which audio signals are recorded to repeat such an operation to control a read-out system by a signal indicating loop reproduction to move read-out position of data to a position traced back in time by a predetermined number of tracks to carry out reproduction up to the position where execution of loop is started to move the read-out position to the position traced back therefrom. Thus, effects similar to the scratch rendition of the record disc of an analog system can be provided.
