Abstract: PURPOSE:To improve the accuracy of tracking control by forming a pit to the shape which is asymmetrical with the center line of the pit at both ends thereof and is point-symmetrical with the central points of the pit. CONSTITUTION:The center line 2 of the pit 1 is also the center line of a recording track. The shape of this pit 1 at both ends thereof is asymmetrical with the center line 2 of the pit and is point-symmetrical with the center 3 of the pit 1. If a spot 4 is formed at the top end of the pit 1 by projection of a light beam thereto, the pit part in the spot 4 exists more on the left side than on the right side width respect to the center line of the spot and, therefore, the quantity of light interference of the left side increases above the quantity of light interference on the right side and the quantity of the reflected light is distributed asymmetrically so as to bias toward the right side with respect to a plane 5. The quantity of the reflected light is distributed symmetrically with a center with respect to the plane 5 and the light is received at an equal quantity in light receiving parts 6L, 6R when the light beam is so projected to the pit 1 as to generate the spot 4 between both ends of the pit 1. The tracking control signal is, therefore, obtd. by comparing the quantity of the light received in the light receiving part 6L and the quantity of the light received in the light receiving part 6R.

Title: Constant-current circuit
Inventor: YOSHIDA YOSHIHIRO
IPC: G05F3/30
Filed: 1981-04-30
Abstract: PURPOSE:To obtain a titled circuit which can operate under low voltages and is suitable for converting it to integrated circuits, by controlling an electric current in such a way that the potential difference across a resistance is equal to the offset voltage of a differentially amplifying circuit which is generated because the current density is different. CONSTITUTION:A constant-current is obtained at a transistor Q8 which is a constant-current source by controlling an electric current IREF flowing into a resistance R12 in such a way that a potential difference DELTAVBE across a resistance R12 is equal to offset voltages of differentially amplifying circuits Q1-Q4 which are generated because the current density is different. In this constant- current circuit, the difference in current density is produced by changing the emitter area of the transistors Q1 and Q2. Since the DELTAVBE due to the difference in current density and the R12XIREF operate so as to balance with each other under the same condition, operations under low voltages become possible.

Filed: 1998-03-17
Abstract: PROBLEM TO BE SOLVED: To promptly close a focus in the case of the occurrence of a focusing error such as displacement of an optical pickup to the outer peripheral side of an optical disk for instance at the time of seeking. SOLUTION: At the time of seeking for moving an optical pickup 3 from a prescribed position (a) for instance of an optical disk 1 to a different prescribed position (b), a DPS 5 moves the optical pickup 3 to an inner peripheral side for a prescribed distance or for a prescribed time and searches a focus at the time of detecting the occurrence of a focus error by a focusing servo. Also, the prescribed distance or the prescribed time is set at a distance or time capable of surely returning the optical pickup 3 into the optical disk in the case that it jumps out to the outer peripheral side of the optical disk 1. Thus, even when the focus error occurs at the time of seeking, the focus is promptly closed and seeking is quickly restarted. That is, time (retry time) after the focus error is generated until starting seeking again is shortened.
