摘要： A focus control apparatus for a multilayer optical recording medium performs an adequate focus jump on a multilayer optical recording medium. Threshold values are set according to the amount of a level change in a focus error signal of a loaded multilayer optical recording medium, and focus jump control is conducted based on the result of comparison between the level of the focus error signal and the set threshold values. Positive and negative threshold values to be compared with the level of the focus error signal to detect a zero-crossing point of the focus error signal are set in accordance with the amount of a level change in the focus error signal, after which an acceleration operation of the focus actuator is started in response to a focus jump instruction to shift the focus position of read light for a focus jump, the acceleration operation is stopped in accordance with zero-crossing detection, a deceleration operation of the focus actuator is started thereafter and is stopped in accordance with zero-crossing detection, so that the operation returns to the focus servo operation.

摘要： An operation mode is first selected in which tunes recorded in a digital audio disk are sequentially reproduced. Reproduction-undesired tunes are selected by operating a manipulator for stopping reproduction of a currently reproduced tune and starting the next tune during every reproduction of the reproduction-undesired tunes so that their numbers are stored in a memory. In subsequent reproductions, the number of each tune going to be reproduced is compared with the numbers of the reproduction-undesired tunes stored in the memory and the tune is skipped if its number is included in the stored numbers.

摘要： A method for controlling the operation of a disk player pickup control system includes the steps of reading position data representing the present position of a pickup from a disk, calculating the distance from the present position to the home position of the pickup according to the position data thus read, and moving the pickup to the home position according to the distance thus calculated. The above-described method for operating the control system is particularly advantageous in that it allows the pickup of a disk player, which does not include a mechanical limit switch, to be moved to the home position.
