A recorder has a recording head which uses light for information recording to a recording medium. The recording head has a slider and an optical waveguide. The slider moves relative to the recording medium while floating thereon. The optical waveguide is provided in the slider and has a refractive index difference of 20% or more between a core and a cladding.

Processing is carried out assuming that a picture structure is fixed to I picture and P picture and that motion compensation value is fixed. Header analyzing section 11 identifies the type of picture of input video code in case of P picture, IDCT section 14 carries out IDCT to calculate a differential value of each block. An adder 15 adds the differential value and a motion compensated block obtained by motion compensating, by forward prediction section 18, a video code of preceding frame stored in a preceding frame section 16. Thus, an image is expanded and reproduced. By fixing the picture structure to I picture and P picture, it is possible to dispense with judgement whether or not the picture is B picture and backward prediction or bidirectional prediction in processing of the B picture.

On expanding, into a video reproduction and an audio reproduction synchronized with each other, a compressed video and audio signal comprising subsampled video and audio codes and indicating a frame rate and an indicated high frequency compression factor, presubsampled video codes are reproduced in compliance with the frame rate and decoded into decoded images. In compliance with a high frequency component compression factor selected from table factors in accordance with the indicated high frequency component compression factor, a dequantizer dequantizes the decoded images into dequantized images. In compliance with another high frequency component compression factor likewise selected, an inverse discrete cosine transform processing unit subjects the dequantized images to inverse discrete cosine transform to produce the video reproduction.
