Title: Optical pickup device and recording and reproducing apparatus
Inventor: FURUYA TAKAAKI
IPC: G11B7/09
Filed: 2004-03-29
Abstract: <P>PROBLEM TO BE SOLVED: To provide an optical pickup device and recording and reproducing apparatus in which optimal recording and reproducing laser beams can be generated for optical recording media of different standards by a single optical pickup device.  <P>SOLUTION: When a liquid crystal control section 29 applies a voltage to a liquid crystal 22, since laser light transmitted through the liquid crystal 22 is not polarized, non-diffracted light 26a is outputted without diffraction in a diffraction grating 23. The non-diffracted light 26a is transmitted through a beam splitter 24 and refracted by an objective lens 25, and forms a light spot 12a on an information recording plane of an optical disk 27. Reflection light reflected on the information recording plane is inversely transmitted through the objective lens 25, is perpendicularly reflected by the beam splitter 24 and reaches a photodetector section 28 wherein a photodiode is integrated. The photodiode generates an electric signal corresponding to the quantity of incident light, and a non-illustrated signal processing section extracts data recorded on the optical disk 27 from the generated electric signal.  <P>COPYRIGHT: (C)2006,JPO&NCIPI

Abstract: <P>PROBLEM TO BE SOLVED: To provide a novel polarization beam splitter which does not damage in spite of irradiation particularly with high-output laser beam, more particularly deep ultraviolet light.  <P>SOLUTION: The optical axis of a KAB crystal 1 and an incident direction of rays are deviated by ξ=28.6°. Therefore, S polarized light advances rectilinearly but P polarized light progresses in a direction inclined by θ=4.414°. The P polarized light and the S polarized light are separated. Since the first face 1a and second face 1b of the KAB crystal 1 incline with ϕs=34.5°, the S polarized light is eventually made incident at an angle ϕs=34.5° with the second face 1b and is therefore totally reflected by the second face 1b. On the other hand, the P polarized light is eventually made incident at ϕp=31.5° on the second face 1b and the angle is a Brewster angle and therefore light transmits the second face 1b without being reflected by the second face 1b, is refracted and emitted at an angle χp=58.5°.  <P>COPYRIGHT: (C)2006,JPO&NCIPI

Then, a load current instantaneous value is taken in at each sampling and a corresponding sine function value is obtained from a sing function value table to calculate the load current instantaneous correction value. This value is added the prescribed sampling times to calculate a load current correction total value which is compared with a load current set value. The instruction value of a delay time that determines the output timing of a trigger signal is controlled according to the difference of the comparison to control the power consumption of the motor 5 within a prescribed range.  <P>COPYRIGHT: (C)2006,JPO&NCIPI
