Abstract
Abstract A reproducing device includes a ROM card, a file control data RAM, a control circuit, and a general purpose computer. The control circuit is a peripheral device of the computer, and the ROM card and the file control data RAM are connected to the control circuit. The ROM card stores a format by which the general purpose computer reads data. The file control data RAM stores file control data of the magnetic disk. Image data recorded in a magnetic disk is read by the control circuit and temporarily stored in the buffer RAM. File control data recorded in the magnetic disk is transferred and stored in the file control data RAM in accordance with the format stored in the ROM card, and the computer reads the file control data from the file control data RAM, and the image data from the magnetic disk, in accordance with that format.
