ABSTRACT:
A method and apparatus for recording and/or reproducing digital image data is disclosed which are compressed by an interleaving process using a logic product code. The method comprises the steps of receiving the digital image data corresponding to one frame; converting the digital image data into a plurality of outer codes and a plurality of inner codes, each of the outer codes having an image information data block and a first additional information data block, and each of the inner code having the image information data block and a second additional information data block; generating a plurality of logic code blocks composed of the outer and inner codes, each of the logic code blocks being used as an error correction code block; dividing each of the logic code blocks into a first storing information portion and a second storing information portion, the first storing information portion having the image information data block and the second additional information data block and the second storing information portion having the first additional information data block and the second additional information data block; and recording the first storing information portion on a middle portion in each track on a recording tape and recording the second storing information portion only top and bottom portions in each track.
