Abstract

PURPOSE:To obtain an inexpensive and large-capacity file memory which is renewable for the user, by providing a renewal data region and a new data region between an index track of the most inner circumference of an unrenewable optical disk memory and the most outer circumference. CONSTITUTION:The most inner circumference track 11 of an unrenewable optical disk 7 is used as an index track, and a renewal data region 12 and a new data region 13 are provided between the index track and the most outer circumference track 14. The data transferred to a file control part 6 via a buffer 5 is converted into a series form by a parallel-series converting circuit 16 via a control part 15 and with a control signal sent from a CPU2 and is sent to an optical disk memory 7. Thus the said data is written into the region 13. If a renewal data exists, after a renewal data list is recorded to a RAM18, said data is written into the region 12. Accordingly, an inexpensive and large-capacity file memory, which is renewable for the user, is obtained.
