| 20090003167 | TRACKING ERROR SIGNAL DETECTION DEVICE AND OPTICAL DISC APPARATUS - A tracking error signal detection device employing a differential phase detection method includes first and second differentiators which remove direct current components in first and second signal groups in which a phase difference between the first and second signal groups changes in accordance with a tracking error signal, and which differentiate the first and second signal groups, first and second analog/digital converters which sample and quantize signals output from the first and second differentiators, respectively, a Hilbert transformer performing a 90-degree phase shift on one of signals output from the first and second analog/digital converters, a delay circuit delaying one of the signals output from the second and first analog/digital converters by an amount of delay equal to that caused by the Hilbert transformer, and a phase comparator calculating a phase difference between a signal output from the Hilbert transformer and a signal output from the delay circuit. | 01-01-2009 |
| 20100080100 | TRACKING ERROR SIGNAL DETECTION APPARATUS AND OPTICAL DISC APPARATUS - A DPD tracking error signal detection apparatus includes the following. Four differentiators remove DC components and differentiate four signal with varying differential phases. The signals are then sampled and quantized by four A/D converters, and output to a non-inverting unit and an inverting unit. A phase inverter/compositor then leaves as-is or phase-inverts the output signals, according to a control signal. The non-inverting and the inverting unit each include two Hilbert transformers that phase-shift the output from the A/D converters, two delay units that delay the output of the other A/D converters to match the delay of the Hilbert transformers, two cross-correlators that calculate the cross-correlation between pairs of Hilbert transformers and delay units, and an adding unit that combines the cross-correlator results and outputs the combined result to the phase inverter/compositor. | 04-01-2010 |
