Title: Device and method for initializing optical recording medium
Inventor: HARIGAI MASATO
IPC: G11B7/0055
Filed: 1996-12-14
Abstract: PROBLEM TO BE SOLVED: To make initialization efficient by densifying and uniformizing a high output laser beam size through a collimate lens, an objective lens and an anamorphic prism. SOLUTION: A high output semiconductor laser LD 1 is made a parallel luminous flux by the collimate lens 2, and is refracted only in the direction parallel to the longitudinal direction of the activated layer of the LD 1 by an anamorphic prisms pair 3 of an anamorphic optical system, and its luminous flux size is enlarged. The enlarged luminous flux is converged on a joined surface of a recording layer 52 of an optical recording medium 5 in parallel by the objective lens 4 through a λ/4 wavelength plate 10'. The luminous flux size of the LD 1 at the time is decided by the focal distances of the used collimate lens 2, objective lens 4 and the magnification of the anamorphic prisms pair 3. At this time, since a beam size becomes 1/2-1/6 of a half-value width of a near view image in the direction parallel to the joint surface of the LD 1, an intensity profile becomes dense.  Thus, the apparently uniformized intensity profile is realized, and the even initialization is performed efficiently.

Filed: 1993-12-29
Abstract: PURPOSE:To always execute optical space transmission with high quality by using a laser diode of the single mode having any oscillation wavelength among preycribed wavelengths so as to avoid the adverse effect of an absorption spectrum. CONSTITUTION:The optical space transmission employing a laser beam is implemented between optical space transmitters 81, 82 and the laser beam generated by the transmitter 81 is emitted via a lens 83 and the transmitter 82 receives the laser beam from the transmitter 81 via a lens 84.

The frequencies for transmission and reception differ from each other in the transmitters 81, 82. In this case, the laser diode in the single mode state having a stimulated wavelength among wavelengths of 770-810nm is employed. As a result, the probability of deteriorated S/N caused when the laser beam approaches an absorbed spectrum region is remarkably reduced.

Filed: 1997-12-22
Abstract: PROBLEM TO BE SOLVED: To grasp position relation between the lens of an image pickup camera and a subject where a signal generating device for generating signals is mounted by comparing the strength of the signals detected by two sensors in two directions, that is, the vertical and the horizontal ones. SOLUTION: The upper right sensor 3a, the upper left sensor 3b and the lower left sensor 3c are fixed on the same plane of the image pickup camera 4 so as to be mutually at equal distance with respect to the center of the lens of the camera 4. A microcontroller part 8 judges that the upper right sensor 3a is more close to an infrared-ray signal generating device 5 than the upper left one 3b and the lower left one 3c when the strength of an infrared-ray signal which is detected by the upper right sensor 3a is larger than those detected by the sensors 3b and 3c in the horizontal direction. The microcontroller part 8 outputs a driving signal for driving the camera part 2 to the direction of the sensor with the detected larger strength to a control part 9.  Thus, the camera part 2 is moved to a position where the strength detected by the respective sensors become equal so as to photograph the subject.
