Title: Optical head device
Inventor: YASUZAWA TAKUYA
IPC: G11B7/09
Filed: 2000-03-22
Abstract: PROBLEM TO BE SOLVED: To provide an optical head device capable of correcting an aberration to be generated when light passes through a substrate on which a birefringence diffraction grating layer is provided, thereby preventing a reduction in the sensitivity of a focus error signal. SOLUTION: Light emitted from a semiconductor laser 1 is incident onto a triangular prism 19, and reflected from a polarizing beam splitter layer 20 formed between a substrate 9 and the triangular prism 19. The light is then collimated by a collimate lens 3 and converged onto an optical disk 63 by means of a converging lens 5. A returning light from the optical disk 63 travels along the same optical path but in the opposite direction to be again incident onto the triangular prism 19. A portion of the original polarizing component passes through the polarizing beam splitter layer 20, while most of the polarizing component to be generated by Kerr effect passes therethrough.  The light that has passed through the polarizing beam splitter layer 20 is reflected and diffracted by a birefringence diffraction grating layer 70 that has an aberration correcting function, so that an aberration generated when passing through the substrate 9 is corrected with respect to the +1st order diffraction light, and then received by a photodetector 71.

Abstract: PROBLEM TO BE SOLVED: To provide a transmission reception system, where more information is transmitted at the same frequency band by solving the problem that the transmission information quantity cannot be increased, when the frequency band is limited in a transmitter sending a digital signal. SOLUTION: The transmitter 1 uses a modulator 4 conducting an m-value QAM modulation to assign a 1st data stream consisting of n-value data and 2nd and 3rd data streams, consisting of p-value data to a signal point group resulting from grouping signal points on a signal space diagram and transmits a QAM modulation signal with a modified m-value. A demodulator 25 of a 1st receiver 23 demodulates the 1st data stream consisting of the n-value data, a 2nd receiver 33 demodulates the 1st and 2nd data streams, and a 3rd receiver 43 demodulates the 1st, 2nd and 3rd data streams. Thus, by using even a receiver having only demodulation capability of the n-value data (n<m) when receiving the modified multi-value (m-value) modulation wave, a transmitting device which can demodulate the 1st data stream consisting of the n-value data is obtained.
