摘要： A disk player reads data read from a disk after temporary storage in a memory and outputs the read data and is capable of preventing the memory from becoming empty by a retry operation for reading data, thereby avoiding a sound failure. When an address whose data is not correctly readable is present on a disk, the address information of that address is stored, and when the same disk is played again, the data reading operation for the new address is performed before the amount of remaining data in the memory becomes too small at the time the next reading address is address whose data is unreadable based on the address information. When at least the same disk is played again, therefore, the memory may not become empty, thus preventing a sound failure from occurring.
摘要翻译：磁盘播放器在临时存储在存储器中之后读取从磁盘读取的数据，并输出读取的数据，并且能够通过用于读取数据的重试操作来防止存储器变空，从而避免声音故障。当磁盘上存在数据不正确的地址时，存储该地址的地址信息，当再次播放同一磁盘时，新的地址的数据读取操作在在下一个读取地址是基于地址信息的数据不可读的地址时，存储器变得太小。因此，当再次播放至少相同的盘时，存储器可能不会变空，从而防止发生声音故障。

摘要： A temperature inside the information reproducing and recording apparatus is always monitored and it is judged whether the temperatures is a proper operation start temperature, a stop temperature or a restart temperature or not. Based on this judgement, the start and the like of the reproducing and recording operation is properly controlled. Further, with respect to the reproducing and the recording of the information, their respective proper operation temperature ranges are set individually.

摘要： When a detection device detects any kind of change regarding track recording after the start of the track recording, a grouping instruction is given to information attaching and generating device. Then, the information attaching and generating device attaches the same group name information to a group, in which a track where the recording has been started in an information recording medium to a track recorded at the point when the grouping instruction has been received are made to be the same group, and group control information is generated. Therefore, since the grouping is automatically performed by any kind of change regarding the track recording, a user can omit the operation that he/she performs the grouping by himself/herself, and thus the operation load of the user can be reduced.
摘要翻译：当检测装置在轨道记录开始之后检测到关于轨道记录的任何种类的改变时，给信息附加和产生装置给出分组指令。然后，信息附加和生成装置将相同的组名称信息附加到其中在信息记录介质中已经开始记录的轨道到已经接收到分组指令时记录的轨道的组成为同一个组，并生成组控制信息。因此，由于通过关于轨道记录的任何种类的改变来自动执行分组，所以用户可以自己省略他/她执行分组的操作，从而可以减少用户的操作负担。

摘要： An unbalanced waveform of a tracking error signal is automatically corrected within a short period of time. A peak value and a bottom value of a tracking error signal are obtained by a peak-hold circuit and a bottom-hold circuit, respectively. Based on the peak value and the bottom value, an amount of offset measured from a reference level and an amplitude of the tracking error signal are computed. An adjustment value is computed for correcting the unbalance between the peak value and the bottom value based on the amount of offset and the amplitude of the tracking error signal. The adjustment value is fed back to a tracking balance circuit so that the waveform of the unbalanced waveform of the tracking error signal is corrected.
