ABSTRACT:
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.
