摘要： A disk cartridge and a disk cartridge drive mechanism are disclosed. The disk cartridge includes a flexible recording disk with a hub at the central portion thereof, and a cartridge case containing the recording disk, with the hub having formed therein a chucking hole and a positioning hole. In order to rotate the recording disk by loading it into the disk cartridge drive mechanism, the chucking hole is defined by two straight-line portions that intersect to form a corner against which a spindle shaft of the disk cartridge mechanism is capable of being pushed, and the positioning hole is defined by a contact portion with which a drive pin of the disk cartridge drive mechanism is capable of coming into contact only in the direction of rotation of the recording disk.

摘要： An optical information writing apparatus includes a written state determination unit and a write strategy setting unit. The written state determination unit determines whether an area of an optical recording medium in which information is to be recorded is used or blank. The write strategy setting unit sets a write strategy in accordance with whether the area is used or blank. When the area is used, the write strategy setting unit performs an overwrite operation before setting the write strategy.

摘要： An optical disk drive capable of detecting a surface deviation of a disk during a very short period includes an analog-to-digital converter (ADC) converting a focus error signal output from a pickup into digital data, and a central processing unit (CPU) writing an output of the ADC to a memory during one rotation of a motor according to a timing of a pulse signal output from a spindle motor. After that, the CPU reads data written to the memory and obtains a sine curve that minimizes the sum of squares of errors among data by a least square method. The CPU obtains a peak-to-peak value of the obtained sine curve and compares the peak-to-peak value to a predetermined threshold value, thereby determining the existence of the surface deviation of the disk.
