    摘要： A method for setting a sound recording level by reproducing a signal recorded on a recording disk (1) is provided in which a playing operation and a track jumping operation are alternately performed by a disk playing unit (A). During each playing operation, peak values of the audio signal recorded on the disk (1) are sampled and stored. The sound recording level is set according to an average of the sampled peak values. In addition, where several pieces of music are recorded on the disk, the number of tracks jumped during the track jumping operation may be changed in accordance with the playing time of each of the recorded pieces of music. Also, the number of tracks jumped during the track jumping operation may be changed as the jumping operation progresses toward the outer circumference of the disk.

    摘要： A disk player having digital processing of error signals (FE,TE) in a servo system utilizes an A/D converter (12). The relatively small closed loop error signals are amplified by a predetermined amount above that for the open loop error signals prior to conversion in the A/D converter (12), and the coverter (12) output representating the digitized small error signals is amplified by a predetermined amount below that for the digitized open loop error signals. While the overall gain in the servo system is substantially the same for the closed loop and open loop error signals, the small closed loop error signals are greatly expanded in range at the converter (12) input to permit the same A/D converter (12) to convert both the open loop and the closed loop error signals faithfully.

    摘要： A method for setting the loop gain in a focusing servo loop (5,6,8,9,7) of a disc player. The loop is opened and the objective lens is moved repeatedly up and down about the focusing point while the disc (1) is slowly rotated, under the control of a system controlled (7), thereby generating an S-shaped focusing error curve. The S-shaped error curve is sampled and a loop gain is determined based on the sampled values. If an eject instruction occurs during the loop gain setting process, a braking pulse is applied to a spindle motor (2) for stopping the disc rotation.
