Abstract
An optical disk drive for reproducing digitally compressed image data is configured such that during high-speed fast forwarding or fast reversing of an optical disk, only the field or frame compressed by the in-field or in-frame coding is reproduced. At the same time, the decoded same field or same frame is repeatedly displayed every plural number of times. Alternatively, the rotating speed of the optical disk is increased relative to that of normal reproduction to raise the transfer rate of the reproduced data, whereby the same field or same frame is displayed a reduced number of times, such as once.
