Abstract

PURPOSE:To avoid the destruction of a data, by carrying out a collation of the file names in case a disket is replaced with another disket and informing a user an improper disket if any in the form of an error. CONSTITUTION:A disket 14 storing plural file names is loaded to a floppy disk device FDD 13, and a file in the disket 14 is opened out of a job which is being executed under the control of a CPU. Thus an OPEN signal is supplied to an AND circuit 15, and the gate of the circuit 15 is opened. A file name stored in the upper digit of a register 16 is supplied to terminal A of a comparator 20. The comparator 20 compares both fine names. When no coincidence is obtained between the file names, an error signal is sent to the CPU via an interface circuit 11.
