ABSTRACT:
In a digital VCR having a plurality of magnetic heads for recording digital video signals in slant tracks on a magnetic tape, a recording circuit divides a digital input video signal into data blocks and performs an orthogonal transformation, such as the discrete cosine transform, in order to compress the data. The resulting blocks of coefficient data are recorded so that all coefficient data of a given block are recorded together by one of the magnetic heads on a single track. In this way, propagation of errors caused by head clogging or drop-outs is prevented.
