Title: Optical information reading device
Inventor: OUCHIDA SHIGERU
IPC: G02B7/28
Filed: 1988-04-27
Abstract: PURPOSE:To decrease the number of parts in a magneto-optical detecting optical system and a servo optical system by arranging an optical element to have a diffracting surface, with which a reflected light beam from an optical information recording medium is specified on an optical path to pass through a polarizing beam splitter. CONSTITUTION:An incident light to be made incident on a diffracting surface 21 in a left side is separated into a diffracted light beam KL and a transmitted light beam TR by a diffraction grating 25. An incident light to be made incident on a diffracting surface 22 in a right side is also separated into a diffracted light KR and a transmitted light beam TR by a diffraction grating 25. When the incident light beam is in a condition (A) which is same as the emitting light beam of a semiconductor laser 1, the polarizing angle of the incoming light beams, which are mode incident on the diffraction gratings 24 and 25, keeps the condition of alpha=45 deg.. Then, the diffracted light beam KL and transmitted light beam TL in the left side and the diffracted light beam KR and transmitted light beam TR in the right side are wholly made equal. However, the polarizing angle alpha is changed according to the condition of a magneto-optical disk and a polarizing direction is changed for a case that a signal is '1' (a condition B) and a case that the signal is '0' (a condition C). Thus, a signal condition on the magneto-optical disk can be detected. On the other hand, a light beam to pass through a central emitting surface 23 can be used as a signal for servo.

IPC: H04N19/625
Filed: 1995-04-28
Abstract: PURPOSE: To decrease a circuit scale of the orthogonal transformation device such as a discrete cosine transformation device. CONSTITUTION: A two-port memory is used as a transposition memory 7 where output data from a linear DCT arithmetic circuit 6 are transposed and a transposition memory control circuit 10 reads written data out one - (2N-2) clocks before the writing of one block is completed and then writes following blocks in parallel to their read successively to the writing. The respective blocks are written while the row order and column order are inverted alternately for every block, and the respective blocks are read out in order different from the writing order of the blocks.  For the operation, a circuit 12 which generates the read address 22 of the transposition memory 7 generates the read address by alternating two kinds of method for a case wherein the address increase, one by one, and a case wherein the address increase by N at each time at every (N×N)th time and generates the write address by delaying the read address by a time of one of 1 to 2N-2 clocks through a delay circuit 13.

The light introduced to the main signal detecting system passes through a diaphragm 7 and is received by a photodetector 9 after their bit information is selected by an analyzer 8. By making the track direction shown by the arrow coincident with the longitudinal direction of the stopping cross section 12 by utilizing the relation between the magnetic domain which is the bit information and the spot formed by the objective lens 4, oppositely rotating Kerr rotating components which become noise components are cut off. Therefore, the S/N is improved and the bit error rate can be improved remarkably.
