ABSTRACT:
The present invention provides a system for causing an optical beam to impinge on a spot on an optical medium, while keeping an optical head apparatus in an essentially stationary position, such that it eliminates the need for a tracking function to move an optical head apparatus in order to direct an optical beam between tracks or to an location on the optical medium.
