Abstract

PURPOSE:To obtain a file of updatable large capacity, by selecting whether an optical disc memory or a magnetic disc memory, in a file device using the optical disc memory and the magnetic disc memory. CONSTITUTION:Data is transferred to optical disc memory 7 from picture buffer 5, where picture information is entered, under the control of file control part 6 according to instructions of CPU2, thereby recording picture information. In respect to update, picture information in the address designated on picture buffer 5 is recorded in magnetic disc memory 8, and update information on magnetic disc 8 is read out at the reproducing time in accordance with the label which is provided on magnetic disc 8 and indicates the update position, and the subaddress from optical disc 7 is collated with the subaddress from magnetic disc 8 each time one-subaddress components are reproduced from optical disc 7; and when they coincide with each other, reproduced information from magnetic disc 8 is replaced with information from optical disc 7 in the subaddress unit and is transferred.
