摘要： A disk recording or playback device first sets a target region, and a pickup (3) is moved toward the disk inner periphery to turn on a sensor switch SW. The pickup (3) is thereafter reversely moved, and further caused to overrun for a predetermined period of time from the position where the sensor switch is turned off. The pickup (3) is returned after reading the address reached by overrunning. If the address is closer to the disk outer periphery than the target region, the overrun time is decreased, and the movement of the pickup (3) toward the lead-in area is repeated again. When the overrun time becomes not greater than a specified value and if the address then read is closer to the disk outer periphery than the target region, the direction of overrun is reversed toward the disk inner periphery. The overrun time enabling the pickup to reach the target region accurately is saved.

摘要： A computer system comprises a microcomputer (20) and external memory means in communication with the microcomputer (20) for storing various programs and various items of data. The microcomputer (20) comprises a nonerasable ROM (22) having stored therein a basic program and basic data indispensable to the operation of the system, a RAM (23) for storing various programs or various kinds of data, a CPU (21) for executing programs and processing data, and an interface circuit for providing communications with external devices. The external memory means has stored therein a modification program for modifying a portion of program data contained in the basic program, and a modification starting address indicating a location in the basic program where the modification of the basic program by the modification program is to be started. The CPU (21) has an address interrupt function for processing an interrupt at a predetermined interrupt address. The microcomputer (20) modifies the basic program by transferring the modification program from the external memory means to the RAM (23), storing the modification starting address in the CPU (21) as the interrupt address, and executing a command to jump to a head address of the modification program in the RAM (23) for an address interrupt.

摘要： Identification codes comprising consecutive numbers are assigned to all disc holding grooves of a magazine. A memory 202 of a microcomputer 200 has a first storage area for storing the identification code of the magazine groove 31 positioned as opposed to a disc insertion-discharge portion 4 or playing portion 9, and a second storage area for storing the identification code of the groove 31 accommodating the disc to be played. The direction of rotation of the magazine is determined by an arithmetic procedure based on the two identification codes stored in the first and second storage areas and on the difference in position between the insertion-discharge portion 4 and the playing portion 9 around the center of the magazine.

摘要： A disc player including a fixed chassis provided with a disc transport tray reciprocatingly movably, and a movable chassis liftably supported by the fixed chassis. The movable chassis has mounted thereon a disc rotating turntable and a signal reproduction pickup reciprocatingly movable along a radial line of a disc on the turntable. The tray and the movable chassis are driven by a loading motor serving as a common power source. First and second power transmission routes from the motor to the tray and movable chassis are changed over to each other by an intermediate gear mechanism provided between the tray and the movable chassis.

摘要： When data readout from a disk of a CLV type by a pickup is suspended, an address in which data is read by the pickup at that time point is stored in a RAM. Prior to restart of the data readout from the disk by the pickup, a specified rotational speed of the disk corresponding to the address stored in the RAM is read from a table memory and the disk is preliminarily rotated at the specified rotational speed. The data readout at the transition time from a servo-off state to a servo-on state is started more promptly.

摘要： A signal recording apparatus includes a battery voltage detecting circuit. The battery voltage detecting circuit detects the voltage value of a battery. When a record button provided on an operation panel is pressed, a syscon detects, for 160 ms, voltage values given from the battery voltage detecting circuit. The detected voltage values are stored to a DRAM. An average is calculated of the voltage values of for 160 ms by using the DRAM. The syscon compares the averaged voltage value with a threshold A that recording is possible for one disk. When the averaged voltage value is equal to or higher than the threshold A, the syscon directly starts recording. When the averaged voltage value is lower than the threshold A, an insufficient remaining capacity of the battery is displayed on a liquid crystal panel by a display controller.

摘要： A disk recording or playback device first sets a target region, and a pickup (3) is moved toward the disk inner periphery to turn on a sensor switch SW. The pickup (3) is thereafter reversely moved, and further caused to overrun for a predetermined period of time from the position where the sensor switch is turned off. The pickup (3) is returned after reading the address reached by overrunning. If the address is closer to the disk outer periphery than the target region, the overrun time is decreased, and the movement of the pickup (3) toward the lead-in area is repeated again. When the overrun time becomes not greater than a specified value and if the address then read is closer to the disk outer periphery than the target region, the direction of overrun is reversed toward the disk inner periphery. The overrun time enabling the pickup to reach the target region accurately is saved.
