摘要:
A process for accessing disk tracks in an optical storage disk using a laser beam passed through an acousto-optic deflector which generates an undeflected beam and at least one deflected beam both of which are focussed on the surface of the disk. The deflected beam is used to read or write data and the undeflected beam is used to follow a servoing structure on the disk.
