ABSTRACT:
An apparatus for reading and writing information on a laser writable rotatable storage medium employs a single laser source. Part of the laser beam is diverted and made to move in an oscillatory manner across an edge of an embedded track. The other portion of the beam is used for reading and writing. To avoid overloading reading detector circuits, an enable switch is provided which responds to read/write control signals.
