摘要： Prevention of deletion of data in an unintended recording layer of an optical disc is ensured even when servo deviation occurs while controlling data reproduction. A light source outputs a light beam with light intensity according to a driving current on which a high frequency signal is superimposed. The light beam is collected on a recording layer of an optical disc. As triggered by detection of servo deviation during data reproduction, a light intensity controller adjusts a superimposed amount of the high frequency signal in the driving current to suit to a specific recording layer with the lowest reproduction tolerance in the optical disc and thereby controls the light intensity of the light beam output from the light source.
摘要翻译：即使在控制数据再现时发生伺服偏差，也能够确保在光盘的非预期记录层中删除数据。光源根据叠加有高频信号的驱动电流输出光强度的光束。光束被收集在光盘的记录层上。由于在数据再现期间由伺服偏差的检测触发，光强度控制器调整驱动电流中的高频信号的叠加量，以适应光盘中具有最低再现容限的特定记录层，从而控制光强度从光源输出的光束。

摘要： A data-storage apparatus, a data-storage method and a recording/reproducing system are provided, which effectively use the time elapsing before data is transferred to be written in a recording medium, such as disc-seeking time and disc-rotation standby time, thereby to raise the speed of transferring data. A hybrid storage apparatus has two storage areas, i.e., a disc and a nonvolatile solid-state memory. The disc and the memory have a disc cache area, a system area, and a user area each. If data is transferred from the host apparatus, it is written into the cache area of the nonvolatile solid-state memory that can be accessed at high speed for the first super cluster. While the data being so written, the head is moved to a prescribed position. Any data coming after the head is moved to this position is written into the cache area.
