28 February 1997 Tracking and moving beam control in optical recorders
Author Affiliations +
The way of laser beam control is offered at optical recording, at which the exact moving to next and subsequent tracks is realized without interrupting of tracking. Error signals are modified in such a manner that stimulate it to change a position of stable balance from one track to another one and so on. The advantage of this moving beam control is accuracy and independence of drive parameters.
