Abstract

A data compression system includes a data array storage device, a coding device, a retrieving and recording device and a recording controller. The data array storage device stores both the input data to be compressed and the input data coded by the coding device. The recording controller determines the character strings recorded by the retrieving and recording device by discriminating between character strings on the basis of the length of the matched character strings beginning from an intermediate character of the matched character strings. The coding device then codes the matched character strings using the length and position of the recorded character strings.
