ABSTRACT:
A write/read head comprises a laser whose resonator faces are formed by the storage medium and by a curved reflective surface which is positioned at a nominal distance from the medium and has a described residual radiant transmittance and a radius of curvature which is greater than the nominal distance. A mode diaphragm is provided between the active medium of the laser and the storage medium. Optical detector elements for the acquisition of position control signals and data read-out signals are arranged outside of the reflective surface and are symmetrically arranged with respect to the optical axis of the laser.
