Abstract

PURPOSE: To enable the accurate alignment to the read-in position of track each head, by aligning the magnetic heads inependently for read-in or write-in.
CONSTITUTION: The head 1 is placed at the tip of the head arm 2, the carriage 3 is at the middle, and the coil 5' is at the rear incorporatedly, and the guide rails 8, 8' to horizontally introduce the head 1 are provided at the both sides of the carriage 3'. A plurality of head arms 2 with this constitution are piled up parallelly in matching with the disc 11, and a pair of support rollers 4" are placed on the carriage support stand 9 to the carriage 3' each head arm 2, the guide rails 8, 8' of the carriage 3' are placed on it, so that the upper surface can press the shaft of the roller 4''' with the spring 13. With the instruction signal to read in or write in the disc 11, a current flows to the coil 5' each head, so that the head 1 can be reached to the read-in position of the disc 11 accurately independently of each disc.
