Abstract: In an information recording medium recording method, recording is interrupted, in recording on an information recording medium, when a predetermined interruption condition is met. A signal recorded in a recorded area is played back and a recording signal playback waveform signal is obtained. Error information indicating an error between a reference waveform signal derived by partial response equalization of a data string and the recording signal playback waveform signal is obtained. A recording condition is corrected on the basis of the error information. A recording/playback apparatus and information recording medium are also disclosed.

Abstract: Reproduction signals include patterns for which recognition errors are likely. With respect to such patterns, probable error patterns are prepared. Tables showing correct patterns and error patterns are prepared, and evaluation values accurately representing signal quality are calculated. In an apparatus using a PRML method, discrimination data and a plurality of predetermined bit sequence pairs are examined to detect matching. A bit sequence and corresponding two ideal responses are calculated. Euclidean distances between the two ideal responses and equalization signals are obtained, and the difference between the Euclidean distances is further obtained. A quality evaluation value of a reproduction signal is calculated based on a mean value, a standard deviation, an appearance probability of the predetermined bit sequence, and a Hamming distance between the predetermined bit sequence pairs.

Abstract: A test pattern including a first test mark which is one unit-record-length longer than a shortest mark among modulating codes and a second test mark which is two or more unit-record-lengths longer than the shortest mark is recorded under a plurality of recording conditions (step S2). The recorded test pattern is reproduced (step S3), and based on a plurality of reproduced signals thus obtained, recording conditions allowing the first test mark and the second test mark, respectively, to be suitably recorded are selected (step S4). A recording condition for the shortest mark is determined by inference based on the recording conditions of the first test mark and the second test mark.

Abstract: A line buffer unit stores the pixel values of image data for respective lines in synchronism with pixel clocks and a horizontal sync signal. An output counter generates a coordinate value to specify a pixel position in second image data based on the count value of predetermined clocks and the horizontal sync signal, and a data request unit converts the generated coordinate value into a pixel position in input image data on the basis of the set scale value. The pixel values of pixels required for arithmetic operations are acquired from the line buffer unit based on this pixel position, and an arithmetic unit calculates the pixel value of a pixel corresponding to the coordinate value. When the arithmetic unit is not ready to execute the arithmetic operation of the pixel value, generation of the coordinate value by the counter is stopped until the arithmetic unit is ready to execute the operation.
