ABSTRACT:
Disclosed is a method for recording and reproducing compressed data on and from a recording medium, in which, when recording and reproducing compressed data compressed by a data compression factor n, the recording medium is divided into successive blocks, each thereof corresponding to a unit recording/reproducing time T, and, when the blocks are designated as D11, D12, . . . , D1N, D21, D22, . . . , D2N, . . . , DM1, DM2, . . . , DMN (where N is an integer smaller than n, and M is an integer), the compressed data are then recorded and reproduced in the order of D11, D21, DM1, D12, D22, . . . , DM2, . . . , D1N, D2N, . . . , DMN, whereby the compressed data ca be recorded and reproduced without changing the structure of mechanical and control systems of a CD, a DAT, etc. used to record and reproduce ordinary data on and from the recording medium.
