Recording device and recording method

摘要

Disclosed is a recording device for recording data in a recording/reproduction device using a recording medium in which the recording-rate performance showing the recordable data quantity per unit time varies area to area. The recording device comprises a data memory unit for temporarily storing data to be recorded; a data quantity management unit for managing the quantity of data in the memory unit, and requesting execution of writing data in the recording medium; a medium area management unit for managing an available area in the recording medium, and deciding a data write position; and a data transfer control unit for controlling transfer of data from the data memory unit to the recording/reproduction device according to the write position generated by the medium area management unit. The medium area management unit includes an area-division management means for dividing the recording medium into plural speed areas of different recording-rate performances, and managing the speed areas. The data quantity management unit includes a recording rate control means for setting a rate of recording the data stored in the data memory unit according to the quantity of the data stored in the data memory unit. The speed areas on which data are to be recorded are switched on the basis of the recording rate set by the recording rate control means. Therefore, the medium is used efficiently without being restricted by the recording-rate performance of a lower-speed area in the medium. <IMAGE>
