摘要： Systems and methods are provided for clocking scheme to reduce nonlinear distortion. An example system may comprise at least two processing paths, each comprising at least one circuit exhibiting nonlinear behavior. Nonlinearity may be managed during processing of signals, such as by assessing effects of the nonlinear behavior during the processing of signals, and controlling clocking applied via at least one path based on the assessed effects, to reduce the effects of the nonlinear behavior during the processing of signals, eliminating the need for post-processing corrections. The controlling of clocking may comprise adjusting timing of a clock applied in the at least path, such as by introducing a timing-delay adjustment to a clock when the clock is applied to a circuit after the circuit exhibiting nonlinear behavior. A timing-advancement may be applied to signals processed via the at least one path, particularly before the circuit exhibiting nonlinear behavior.

摘要： An image capturing apparatus comprises an image capturing unit that includes an image sensor that has an effective pixel region and a reference pixel region which outputs a reference signal for correcting an output signal of the effective pixel region. In a case where a predetermined condition is satisfied, a reduction unit reduces a data amount of reference pixel region data that corresponds to the reference pixel region in an image data obtained by the image capturing unit. A recording unit records the image data after the processing performed by the reduction unit.

摘要： Hardware-based methods and apparatus are provided for inter-track interference mitigation in magnetic recording systems using averaged values. Inter-track interference (ITI) is mitigated in a magnetic recording system by obtaining ITI cancellation data; and providing the ITI cancellation data for ITI mitigation, wherein the ITI mitigation is performed in combination with an averaging procedure for one or more of ITI mitigation of averaged data and averaging of ITI mitigated data. The sector is optionally decoded using the ITI mitigated samples. Samples for one or more side track sectors can also be averaged. The averaged side track samples can be provided as ITI cancellation data for ITI mitigation. The averaging procedure optionally applies a scaling factor to each read value.

摘要： First data representing user data and third data use the same error correction codes. The first data has a first error correction block structure and the third data has a second error correction block structure. That is to say, the first data and the third data have their respective error correction block structures proper for them. In particular, the recording density of the third data is made less dense than the recording density of the first data, and the number of correction codes in the first error-correction block is set at a multiple of m whereas the number of correction codes in the second error-correction block is set at n/m times the number of correction codes in the first error-correction block so that a data-piece count in the second error-correction block is also n/m times a data-piece count in the first error-correction block. As a result, it is possible to provide a good technique of recording shipping-time information onto a high-recording-density disc.

摘要： According to the present invention, it is intended that the recording can be executed normally even against small vibrations to which a servo error signal detecting circuit cannot respond. A recording apparatus according to the present invention includes an optical head (12) for receiving a reflected laser beam (LREF) obtained when a laser beam (LIRR) is irradiated on a CD-R (10). This recording apparatus further includes a gate circuit (31) to which an output signal (SRD) of the optical head (12) is supplied and a level comparing circuit (34) for comparing a value of an output signal (DTAU) of this gate circuit (31) with a predetermined reference value (DTH). Upon recording, the gate circuit (31) is controlled in such a manner that a signal of a predetermined period ts may be outputted from the output signal (SRD) supplied from the optical head (12) to the gate circuit (31) as the output signal (DTAU). An output signal (SCMP) of the level comparing circuit (34) is outputted as a detected result of vibrations of the CD-R (10) or vibrations of the optical head (12).
