Abstract
PURPOSE: To increase usage efficiency of a memory device used for track shape recording band, by writing in the data transfer from a memory unit using a memory band piece, based on the final data address, in the memory system having two levels of memory unit.
CONSTITUTION: In the data transfer from a magnetic tape device 3 to a magnetic disc device 2, the write-in permission signal WP of a buffer 20 is output to a magnetic tape 3, and the data for one track's share and the final data address EA are written in the buffer 20. On the other hand, when the data write-in for one track's share is finished independently of the write-in operation, the readout permission signal PR is transmitted from a buffer control section 21 with the final data address EA each track, and readout operation is made, the readout data is transferred to a magnetic disc, and it is recorded in the same track.
