Abstract

PURPOSE:To search a reference track swiftly and easily, by recording an address signal on the whole circumference of the reference track by use of a digital signal. CONSTITUTION:This device is equipped with the first register means 241 for storing a formatting address command input from ten keys, etc., and the second register means 243 for storing the number of pulses to be supplied to a shifting motor 18, or a value which is obtained by converting a shifting distance of an optical head 10 to the number of tracks on a disk 11. And, it is also equipped with a coincidence detecting means 242 for detecting coincidence of contens of the first and second register means 241, 243, a means for stopping a shift of the optical head 10 by a coincidence signal of this means 242, a means 32 for superposing the contents of the first or second register means 241, 243 in this case, on a recording signal as an address signal, and a means 25 for recording a signal which has superposed an address signal, on the disk 11.
