摘要： When a code word sequence is generated by converting input data words of p bits into code words of q bits and concatenating adjacent ones of the code words with a merge bit sequence of r bits in order to obtain the best DSV value, according to one aspect, the adjacent code words are concatenated with the merge bit sequence of r bits which is selected, free from the restriction of the minimum run-length of (d+1)T and the maximum run-length of (k+1)T based on the run-length limiting rule RLL(d, k) but permitting the minimum run-length of (d+1)T and the maximum run-length of (k+2)T. According to another aspect, a merge bit sequence to be inserted after a current code word is selected by prefetching the current code word, a next code word, and a further next code word, temporarily concatenating these code words with merge bit sequences of r bits respectively to prepare code word sequence candidates free from the predetermined run-length limiting rule, calculating the DSV values of the code word sequence candidates, selecting one of the code word sequence candidates having a DSV value whose absolute value is closest to zero, and selecting the merge bit sequence between the current code word and the next code word of the selected merge bit sequence candidate. According to a further aspect, the input data words are encoded by a p-q modulation scheme after introducing for a predetermined period, as an input data word, specific data comprising alternating current signals or direct current signals which would cause a modulation device that prefetches only the next code word to output a code word sequence which includes particular frequency components.

摘要： An audio disk has a first audio zone and a second audio zone. In the first audio zone, both of a plurality of tracks each including a single piece of music and a first management information including first control information for allowing each track to be reproduced are recorded. The music is composed of audio data produced from either a linear PCM signal or a signal produced by applying lossless compression to the linear PCM signal. In the second audio zone, music composed of audio signal produced under lossy compression, a plurality of files each storing a signal of a single piece of music subjected to the lossy compression, and second management information including second control information for allowing each file to be reproduced are recorded. Each piece of music stored in each file corresponds to the music included in any one of the tracks in the first audio zone.

摘要： Bits of a first bit sequence are rearranged in a first matrix according to a predetermined arrangement rule. The first bit sequence represents information being a base of a key. Blocks are formed in the first matrix. Each of the blocks has bits, the number of which is smaller than the number of bits composing the first matrix. Logical operation is executed among bits in each of the blocks, and a bit being a result of the logical operation is generated. The logical-operation-result bits are combined into a second bit sequence. The number of bits composing the second bit sequence is smaller than the number of bits composing the first bit sequence. There is a second matrix composed of predetermined third bit sequences. The second matrix is accessed and one is read out from among the third bit sequences in response to the second bit sequence. The read-out third bit sequence is outputted as information representative of the key. The number of bits composing each of the third bit sequences is smaller than the number of bits composing the second bit sequence.
