<P>PROBLEM TO BE SOLVED: To provide a disk device with which high double-speed recording or replay can be performed and to provide a data readout method and a data writing method. <P>SOLUTION: A disk device 1b has a decode circuit 15 for performing decoding processing of data read out from a disk, a data/buffer 14 storing decoded user data and made up of a plurality of banks, and an address generation circuit 31 for writing the user data in the data/buffer 14. The address generation circuit 31 accesses the same column of the plurality of banks and writs data therein and, upon completion of the writing of all of the banks in the same column, accesses the next column and generates an address to write the user data therein. <P>COPYRIGHT: (C)2012,JPO&INPIT |
