Title: Controlling system of data storing device
Inventor: NAKABACHI TAKAO
IPC: G11B7/004
Filed: 1982-06-16
Abstract: PURPOSE:To reduce the reading time with a simple device, by erasing an address and jumping a data block having no address when reading if an error arises when the data is stored after giving an address to each data block. CONSTITUTION:A control part 41 receives an indication of a CPU1 and positions the data of a main memory 2 and then writes it to a prescribed address of an optical disk 44 through an R/W circuit 42. If a writing error is detected 45, the part 41 erases an address. In case a data block containing the erased address is detected 46 when reading, this block is jumped to read out the next block. Thus the logical continuity is assured with a simple constitution. This facilitates an easy access when reading by designating only the address of the head data block and the number of data blocks.
