IPC: G11B7/135
Filed: 1996-03-28
Abstract: PROBLEM TO BE SOLVED: To make an optical head small in size and light in weight, to reduce the manufacturing man-hour and to hardly generate cross talk at the time of utilizing a super-high resolving phenomenon. SOLUTION: A laser beam transmitted from a laser diode 11 is transmitted through grating couplers 12a, 12b and a light shielding band 13 and made incident on a condenser lens 14.

Consequently, the intensity distribution of a light spot converged on the surface of an optical disk 15 by the condenser lens 14 has a side lobe only in the X direction by a super-high resolving phenomenon. X direction is made to be the tangential direction of a track of the optical disk 15.
