Abstract

A magnetic recording apparatus of a digital picture signal comprising a block segmenting circuit for converting an input digital picture signal into data segmented by blocks composed of a plurality of picture elements, an encoding circuit for compressing and encoding the output data of the block segmenting circuit by blocks, and a channel encoding circuit for channel encoding the encoded output data from the encoding circuit, wherein the output data from the channel encoding circuit is recorded on a magnetic tape by a magnetic head mounted on a rotation drum, and wherein the magnetic recording apparatus of digital picture data is characterized in that the track pitch formed on the magnetic tape by the magnetic head is 5.5 µm or less, the diameter of the rotary drum is 25 mm or less, and the rotating speed of the rotary drum is 150 rps or more, the track length per unit time is set to particular value thereby.
A long time recording operation with a compact mechanical unit can be performed and the error in respect with track linearity can be decreased.
