Abstract
An information recording apparatus implements the orthogonal transformation for the input signal on a block-by-block basis, separates each variable-length coded word into a fixed part and separate part individually, records the fixed part into a record block which is established for each block of orthogonal component by starting from the beginning and ending at the prescribed position of the record block, and records coded words of the separate part into remaining portions of record blocks.
