ABSTRACT:
A method for modifying program of a magnetic tape unit comprising a flash memory for storing programs a storage memory and a CPU for executing the programs stored in the flash memory and storage memory is provided. The method comprises steps of storing a program for rewriting program in the storage memory, making a discrimination when a magnetic tape is mounted in the magnetic tape unit whether the magnetic tape is a normally used recording medium or a medium for modifying program, reading a program to be modified reproduced from the magnetic tape into a buffer when the magnetic tape is the medium for modifying program, and erasing the contents of the flash memory by the CPU by use of the program for rewriting program stored in the storage memory to transfer the program to be modified from the buffer to the flash memory. Thus the magnetic tape unit automatically modifies the program even if the operator does not modify or notice the program to the magnetic tape unit by way of a special command or connector, so that no special connector or application program for the host need be provided. Furthermore, the streamer need not be taken out by disassembling a case and the like, so that the operator can modify the programs easily.
