    摘要: A head cleaning device includes a first wiping member, a first drive mechanism, a second wiping member, a second drive mechanism, a common drive source, and control circuitry. The first wiping member wipes a nozzle face of each of a plurality of liquid discharge heads. The first drive mechanism moves the first wiping member to a first wiping position at which the first wiping member wipes the nozzle face and a first retraction position spaced apart from the nozzle face. The second wiping member wipes the nozzle face. The second drive mechanism moves the second wiping member to a second wiping position at which the second wiping member wipes the nozzle face and a second retraction position spaced apart from the nozzle face. The common drive source drives the first drive mechanism and the second drive mechanism. The control circuitry controls the common drive source.

    摘要: The present invention relates to a decoding method and a decoder, a program, a recording-and-reproducing apparatus and a method, and a reproducing apparatus and a method that are suitable for decoding encoded data encoded by using a linear code on ring R. A low-density processing unit performs parity-check-matrix low-density processing, performs linear combination for rows of a parity check matrix included in an obtained reception word, and generates a parity check matrix according to the linear-combination result, thereby reducing the density of the parity check matrix used for decoding, at step S21. Then, at step S22, an LDPC decoding unit performs decoding by using a sum product algorithm (SPA) by using the parity check matrix whose density is reduced through the processing performed at step S21. Where the processing at step S22 is finished, the LDPC decoding unit finishes decoding for the reception word. The present invention can be used for an error-correction system.
