Claims

[Scope of utility model registration request]

A buffer memory section for temporarily recording audio data, etc.; a magnetic disk device having a head for each track for recording the audio data in the buffer memory section and supplying the recorded audio data to the buffer memory section; In an audio offline device comprising a magnetic disk control unit that controls data recording and supply and head switching, a magnetic disk formatting unit formats an arbitrary track of the magnetic disk device into a predetermined number of sectors. and a data transfer end detector for detecting the end of data transfer based on a head switcher and a one-track write end signal output from the magnetic disk device, and the magnetic disk formatting section The data transfer between the formatted magnetic disk device and the buffer memory section is performed by sequentially transferring data from the formatted first sector to the next sector, and then transferring data to the sector immediately before the final sector. When the data transfer is completed, the magnetic disk control section temporarily suspends the data transfer, and the data transfer completion detector outputs a completion signal to the head switch, which causes the head switch to start the next track. An audio off-file device characterized in that it switches to the head of a track and resumes data transfer from the first sector of the next track.
