摘要： Partial information such as the beginning data of each of chapters is read from a CD and written in a HDD 10 at a higher speed than that in a normal reproduction while the normal reproduction is carried out using a buffer memory 8. After the chapters relative to all CDs have been written in the HDD 10, reproduction is carried out in switching between the information remaining in the HDD 10 and the information included in the CD. This configuration makes it unnecessary to record the information beforehand, and permits an unreproduciable blank in reproduction to be filled with audio information during track search or CD change while the reproduction is carried out normally.
摘要翻译： 在使用缓冲存储器8执行正常再现的同时，从CD读出部分信息，例如CD中的开始数据，并以比正常再现中的速度更高的速度写入HDD 10中。在相对于 所有的CD都被写入HDD 10中，在HDD 10中剩余的信息和包括在CD中的信息之间进行切换。 该配置使得不需要事先记录信息，并且允许在轨道搜索或CD改变期间填充音频信息的再生中的无法再生的空白，同时正常进行再现。

摘要： A record medium playback apparatus includes a playback section and a playback control section. The playback control section is adapted to control a playback start position of the program information when the record medium playback apparatus is restarted after power thereof was turned off. The playback control section determines the playback start position of the program information using a first sequence when the record time of the whole program information corresponding to the playback position at the power off is less than a predetermined time. The playback control section determines the playback start position of the program information using a second sequence when the record time of the whole program information corresponding to the playback position at the power off is equal to or longer than the predetermined time.

摘要： Two sum output signals from two sets of the photodetector elements located symmetrically each other with respect to a light-receiving center of the photodetector of the optical pickup are amplified individually by two amplifiers. A focus error signal is generated in accordance with a difference between respective output levels of the two amplified signals. The gains of the two amplifiers are adjusted in accordance with the focus error signal. A predetermined bias voltage is applied to the focus error signal line in the focus servo control means in accordance with the focus error signal.

This focus control apparatus implements such focus jump control as to temporarily release a focus servo on one layer of a loaded multilayer optical recording medium, shift the focus position of read light on another target layer and then restart the focus servo on the another target layer, detects an ambient temperature, sets a drive signal condition according to the temperature detection output, and moves the focus position of the read light under the set drive signal condition. Specifically, this apparatus generates an acceleration signal to start moving the focus position of read light and a deceleration signal to decelerate movement of the focus position of the read light, as drive signals for a focus actuator in order to execute a focus jump operation, detects an ambient temperature of the focus actuator, and sets signal conditions for the acceleration signal and the deceleration signal according to the detected temperature.
