摘要： When a light-receiving element receives a first laser beam, an output power detection unit detects a differential quantum efficiency value of the first laser beam. A control unit judges whether or not an intensity filter and a filter driving unit are operated in accordance with a control signal output from the control unit by using the differential quantum efficiency value from the output power detection unit.

摘要： PROBLEM TO BE SOLVED: To provide an optical disk controller which realizes recording and reproducing at high multiple-speed, and which has less power consumption.
SOLUTION: This optical disk controller 150 is a controller for servocontrolling an optical disk device 101 provided with a disk motor 402 for rotating an optical disk, and an optical head 403 to emit the light beam for recording data on the optical disk and/or reproducing data from the optical disk. This controller is further provided with an adjustable clock output section 123 to output a plurality of clock signals with different frequencies, and a control section 112 to calculate and output signals which shows a controlled variable, by receiving signals from the optical head which shows the amount of deflection from a predetermined target value, and by calculating based on the signals which shows the amount of deflection, in order to servocontrol the light beam of the optical disk device. Based on recording multiple-speed and/or reproducing multiple-speed when the recording and/or reproducing operation of the optical disk device is performed, the adjustable clock output section 123 modifies the frequencies of the clock signals, and the control section 112 calculates synchronizing with the clock signals of the adjustable clock output section.

摘要： PROBLEM TO BE SOLVED: To reduce the time between a completion of a seek and a start of a data read without disturbing read clock signals during the seek by controlling the frequency of the read clock signals so that the frequency becomes the expected one at a seek destination. SOLUTION: A comparator 220 compares the output of a number of revolution compensator 218 and the period of CK signals being frequency divided and controls a variable oscillator 204 through a switch 211 so that the frequency of the CK signals becomes the data reproducing frequency at a seek destination. When the movement of a unit head is completed, a controller turns on a switch to turn on a tracking control, the switch 211 is switched so that the output of a comparator 210 and the output of a phase comparator 202 pass an address section. Even though the response of a disk motor is slow, the frequency of the CK signals is controlled to be close to a data reproducing frequency at the movement completion point of the head unit.
