ABSTRACT:
An optical data storage and readout apparatus having an optical head which includes a light source device for producing laser beams, a device for converging the laser beams on a selected area of a surface of an optical recording medium on or from which information is recorded or read out, and an optical detecting device for detecting signal beams reflected by or transmitted through the selected area of the recording medium which is irradiated by the converged laser beams. The optical head has at least one light-emitting optical fiber which receives at its one end the laser beams from the light source device and emits the laser beams from its other end toward the surface of the recording medium. The optical head further has a plurality of light-receiving optical fibers which receive at their one end the signal beams from the selected area of the recording medium, and transmit the signal beams to the optical detecting device.
