Abstract
A pulsed optical storage system including: rotatable storage means; means for projecting a beam of radiation at the surface of the storage means; means for moving the means for projecting transversely relative to the surface of the storage means; means for sensing the position of the means for projecting relative to the storage means; a radiation source for providing radiation to said means for projecting, including a radiation element, and a switching circuit in close proximity to said radiation element for selectively energizing the radiation element; and a control circuit responsive to the means for sensing for selectively enabling the switching circuit to energize the radiation element to produce pulses of radiation to the means for projecting.
