Title: Optical pickup feed device
Inventor: MATSUNO TOSHIKI
IPC: G11B33/08
Filed: 1984-05-07
Abstract: PURPOSE:To prevent the generation of harmful vibration despite the high-speed shift of an optical pickup by providing a rack and a pinion so that a weight having the same weight as the optical pickup is always shifted in the opposite direction to the pickup. CONSTITUTION:Racks 4a and 4b engage with each other vertically against a pinion 6 and always move in the direction opposite to each other by the revolutions of the pinion 6. Therefore an optical pickup 2 and the weight 10 always move in the opposite directions to each other. When the pickup 2 is accelerated toward the outer circumference (right side) of a disk 1, the reaction due to the force of inertia of the pickup 2 tries to move an optical pickup feed device totally in the left side. In this case, the reaction due to the force of inertia of the weight 10 having the same weight as the pickup 2 tries to move the optical pickup feed device totally to the right side. Thus both reactions are completely cancelled with each other. This prevents the vibration of the optical pickup feed device.
