Abstract

PURPOSE: To obtain the magnetic recorder applicable to the memory unit of a small capacity, by writing and reading out a series of information magnetically in continuous spiral from the part near the center of the surface possible for magnetic recording of a magnetic sheet toward the external circumference.
CONSTITUTION: When the mini-floppy disc 16 is mounted on the spindle hub 7a and the motor 1 is ON, the disc 16 starts continuous rotation with a given number of revolutions. When the photosensor 18 detects the index hole on the disc 16 and connects the clutch 9, the magnetic head 12 moves toward the arrow. With this state, when a signal written in is fed to the magnetic head 12, magnetic recording is made on the disc 16, and when the clutch 9 is switched to reversing, the head 12 returns to the initial position. Further, accompanied with the head 12, the position of coupling of the friction wheels 5 and 6 is changed to keep the circumferential speed of the disc 16 at constant for the part opposed with the head 12.
