摘要： PROBLEM TO BE SOLVED: To realize high-speed and stable focus control of a two-focus head or a disk, having a plurality of information surfaces. SOLUTION: In starting or restarting of a system, when a focal lens is moved close to a disk and then moved away from it, or moved away from the lens and then moved close to it; the amplitude of a S-shaped signal is measured, which appears on FE each time the focal point of the optical beam passes through each information surface, the gain of a focus detection system is switched such that the amplitude becomes a predetermined value, and thus an optimum drawing level is established. Then, when the lens is moved away from the disk from the uppermost point (CD), or when it is moved close to the disk from the lowermost point (DVD), the focus control is operated on the information surface to which the focal point of the optical beam initially reaches and the drawing is completed. Thereafter, once the focus control is set inactive, the speed of the focal lens is increased/decreased, based on the FE signal level and the drawing level established on each information surface, and then the control is shifted to the next information surface.

摘要： PROBLEM TO BE SOLVED: To shorten the production tact by producing the code word for the error correction in the manner of producing i pieces of parity symbol in the information group consisting of m+n pieces of the symbols made from that n pieces of dummy symbols are added to the information word group consisting of m pieces of information symbols, and recording it on the specific annular region as a stripe-stated mark long in the radial direction. SOLUTION: The marking is applied for preventing the pirate edition, and the accurate positional information of the mark is read out to obtain the positional information as the physical feature information of the disk. Then, this information is enciphered and recorded on the disk as a bar-code signal. As the constitution of data in the case of n=1, there are only four columns such as data columns 951a, b, c, d, and next they become ECC columns 952a, b, c, d. The data column 951d becomes 4B of the EDC. The data columns from the 951e to 951z are assumed all equivalently to have 0, then the encode calculation of the error correction code is performed and recorded on the disk as the bar code.

摘要： PROBLEM TO BE SOLVED: To achieve high-speed and stable focus control for a 2-focus head or a disk having a plurality of information faces. SOLUTION: When a convergent lens is moved away from a disk after it is brought close to the disk or brought close to the disk after being moved away at starting or restating the device, the amplitude of an S-shaped signal appearing on a FE for each passing of a converging point of a light beam is measured, the gain of a focus detection system is switched so as to obtain a predetermined amplitude, and an optimal pulling-in level is set. Then, when the lens is moved away from the disk from a highest point (CD) or brought close to the disk from a lowest point (DVD), focus control is operated on an information face first reached by the converging point of the light beam to complete the pulling-in. Then, the focus control is made inactive, and the convergent lens is accelerated/decelerated based on the level of a FE signal and a pulling-in level set on each information face to move to a next information face.

摘要： PROBLEM TO BE SOLVED: To solve such a problem that defective pull-in caused by eccentricity acceleration of a disk and wobbling acceleration is easy to occur by highly increasing the number of rotation of the disk. SOLUTION: When a disk 12 is loaded to an optical disk device, start processing is performed by a microcomputer of a system control, initially, a command of spindle-motor-ON is sent to a DSP 34 from the microcomputer. When the DSP 34 receives the command of the spindle-motor-ON, the DSP 34 outputs the ON-signal from the prescribed port, and starts the spindle motor 13 through a spindle control circuit 14 (S1). After sending the command, the DSP 34 performs speed control referring to FG from the spindle motor 13 so as to become the prescribed number of rotations (S2). The microcomputer sends successively commands to the DSP 34. The DSP 34 performs laser ON (S2, S4), focus control ON (S5, S6, S7), and tracking control ON (S8, S9, S10, S11, S12) in accordance with the command. COPYRIGHT: (C)2006,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To provide an optical head wherein a signal recorded in an optical disk and/or a signal reproduced therefrom has a good quality. SOLUTION: This optical head is provided with a semiconductor laser, a diffraction grating, an objective lens, and an optical detector. A first sub-beam is converged along the scanning direction of the optical head with respect to an information medium on a position before a main beam. A second sub-beam is converged along the scanning direction of the optical head with respect to the information medium on a position after the main beam. The diffraction grating divides the optical beam into the main beam and the first and second sub-beams so as to converge the first sub-beam before the main beam on the outer peripheral side of the information medium more than the main beam, and the second sub-beam after the main beam on the inner peripheral side of the information medium more than the main beam.
