Title: Otical pickup head device
Inventor: KADOWAKI SHINICHI
IPC: G11B7/135
Filed: 1991-04-17
Abstract: PURPOSE:To provide optical pickup head device which can detect stably and satisfactorily a signal, with regard to the optical pickup head device which can record and reproduce or erase optical information. CONSTITUTION:The center line of a reflection type hologram element 61 and a pit train 43 projected onto the hologram element 61 are placed so as to become roughly parallel, and also, the pit train on diffracted light 81a, 81b is placed so as to become roughly parallel to boundary lines 71a, 71b on a photodetector 71. Accordingly, even if a difference of the diffraction efficiency is generated due to a difference of an incident angle of a beam which is made incident on the reflection type hologram element, the beam having am equal intensity variation is made incident on a photodetecting part for outputting a focus error signal or a tracking error signal, respectively to a differential arithmetic circuit, a variation of the diffraction efficiency in the diffraction element is offset and an offset is not generated. Accordingly, a stable servo-operation of the optical pickup head device can be realized.

Title: Optical scanning device
Inventor: MUKOGAWA MASASHI
IPC: B41J2/44
Filed: 1988-04-08
Abstract: PURPOSE:To obtain the high-speed, small-sized optical scanning device which eliminates the need for a correcting lens by reflecting light between two ultrasonic wave elements repeatedly and then projecting the light, and varying its angle of projection by ultrasonic wave vibration. CONSTITUTION:The two ultrasonic wave vibrators 1 and 2 which have reflective films adhered on their surfaces are arranged closely almost in parallel so that the surfaces where the reflective films are adhered face each other; and the light is made incident from the gap of one side, reflected repeatedly between the two ultrasonic wave vibrators, and projected from the other end. Here, when a voltage is applied to the ultrasonic wave vibrators so that they operate in the opposite directions, the angle of reflection of the light beam 7 varies. The variation in the angle of reflection is caused at each reflection point, so variation in angle of emission of the light beam 7 which is emitted by the device finally is obtained by multiplying the variation in the angle of reflection at each point by the number of times of reflection and this angle is sufficiently practical for the optical scanning device. Further, the waveform of the voltage applied to the ultrasonic vibrators 1 and 2 is determined properly to make a scanning speed constant. Consequently, the small-sized, fast optical scanning device is obtained which requires no correcting lens and has no rotary part at all.
