ABSTRACT:
In a digital data recording and reproducing apparatus which digitizes an input video signal, records or reproduces digital data on or from a magnetic recording medium of a recording and reproducing unit of the apparatus and converts the digital data read out of the recording and reproducing unit into an output video signal, a converting circuit is provided, on the input side of the recording and reproducing unit, which receives an input data signal of a larger sampling image matrix size than that for the recording and reproducing unit and divides the input image data signal into constituent sampling image matrix sizes by a predetermined fraction to deliver a divided image data signal at a data rate commensurate with the sampling image matrix size for the recording and reproducing unit, and an inverse-converting circuit is provided, on the output side of the recording and reproducing unit, which receives the divided image data signal and reconstructs it into an output image data signal of the original large sampling image matrix size. Information indicative of positions of the divisional image data from the converting circuit is recorded on part of the magnetic recording medium of the recording and reproducing unit and used by the inverse-converting circuit for the reconstruction into the original sampling image matrix size.
