摘要： The invention is directed at ensuring stable track accessing despite the presence of backlash in a pickup drive mechanism, and at providing a precise track accessing operation not affected by the relative position or relative speed between pickup and carriage at the time a track access start instruction is issued. To achieve this, when the track access start instruction is issued in a tracking condition in which the pickup is following a track on a recording medium, the carriage is caused to begin to move in a track access direction by the action of a coarse actuator, while the pickup is still kept on track of the recording medium by means of a fine actuator. When the position of the pickup relative to the carriage has reached a boundary of a switch-off range preset within a movable range of the pickup or moved outside the switch-off range, the track following action of the pickup by the fine actuator is stopped, and the pickup is moved to the target track by using coarse driving control and, as necessary, fine driving control in collaborating fashion.

摘要： A virtual RAM read address generating circuit (41) generates a virtual address-on the basis of an output signal of a crystal oscillation circuit (36). A phase comparison circuit (39) which performs phase comparison with a write address, and a spindle control circuit (3) which controls rotation of a disk with reference to outputs of a frequency comparison circuit (38) and the phase comparison circuit (39) are disposed. Therefore, a phase error can be fed back to a spindle motor, thereby preventing linear velocity deviation from occurring in a steady state. By using the thus configured reproducing device, the reproduction quality in the case where a disk wherein recording was performed by the CLV system is reproduced by the variable linear velocity reproduction system is ensured, and both high-speed access and low power consumption are realized.

摘要： On a liquid crystal panel, plural areas whose number is larger than that of temperature sensors are defined. In a memory, temperature relation information representing a relation between an output value of a temperature sensor and a temperature of each of the plural areas is stored. A controller acquires the output value of the temperature sensor and estimates, based on the temperature relation information and the acquired output value, the temperature of each of the plural areas. According to this configuration, the temperature of each of the plural areas defined on the liquid crystal panel can be obtained with a small number of temperature sensors.
