Abstract:
A disk apparatus using a disk-like recording medium having a plurality of different recording areas located at different radial positions, comprising:a head unit configured to write digital continuous data in the disk-like recording medium;a buffer memory configured to temporarily store a plurality of input digital continuous data; anda control device configured to control the head unit and buffer memory to time-divisionally write the plurality of digital continuous data in the plurality of different recording areas of the recording medium,wherein said control device writes, while one group of data of the digital continuous data is written in one of the plurality of different recording areas at a write speed not less than two times an average bit rate of the input digital continuous data and said head unit is accessing between the recording areas, another group of data of the digital continuous data in said buffer memory, andwrites, in said buffer memory, said one group of data of the digital continuous data input while said another group of data of the digital continuous data that is stored in the buffer memory is read out therefrom and written into another one of the recording areas at a write speed not less than two times an average bit rate of the input digital continuous data and said head unit is accessing between the recording areas.
