Abstract
PURPOSE: To read and write information on both the sides of an optical information medium without turning over the medium, by coupling a pickup arm rotatably with a rotation driving mechanism.
CONSTITUTION: An optical head 5 is stuck atop of a cranked supporting arm 4, and the read end is coupled with the rotor of a pulse motor 7 fixed to a carriage 6. The carriage 6 is driven, as shown by an arrow A, along guide bars 81 and 82 through the rotation of a scanning driving screw rod 9, and the optical head 5 reads and writes information. Then, the pulse motor 7 is driven to rotate the arm 4 around a rotating shaft RA by 180 degrees, reading and writing information on both the sides of a recording medium 1 without turning over the medium.
