ABSTRACT:
An optical head with a plurality of semi-conductor laser chips for use in reducing inclination or gradient of more than one beam presently falling onto a focusing lens is disclosed. To this end, a double mirror or alternatively beam reshaping means is disposed which has different reflection planes for permitting reflection of a plurality of laser beams incoming from the semiconductor laser chips.
