| titleOfInvention | Disk Units and Signal Processing Methods |
| abstract | A disk device of one embodiment of the present invention includes: a light detector (210, 221, 222) configured to divide and detect reflected light from a disk as a plurality of light detection signals; And a tracking error signal generation unit 2 configured to generate a tracking error signal based on the phase difference between the plurality of light detection signals detected by the light detection unit, wherein the tracking error signal generation unit includes a plurality of tracking error signal generation units detected by the light detection unit. And equalizers 231 and 232 configured to equalize the waveform of the photodetection signal, wherein the equalizer has a frequency gain characteristic of obtaining a gain of 15 dB or more at a frequency corresponding to the shortest pit or shortest mark. |
