Patent ID: 7450817

Claim:
A magnetic tape recording apparatus for recording compressed digital image data onto a track of a magnetic tape by means of a rotary head, comprising: inputting means for inputting the digital image data; extraction means for extracting digital image data for variable speed reproduction from the digital image data inputted by said inputting means; production means for producing, from the digital image data extracted by the extraction means, digital image recording data for variable speed reproduction to be recorded into predetermined areas of a first region positioned substantially at the center of the track and a second region positioned at a position which is traced upon variable speed reproduction in a track positioned in the neighborhood of the track; and recording means for recording the digital image recording data for variable speed reproduction produced by said production means into the first and second regions, wherein said first region comprises three pieces of digital image data recorded at eightfold speed, each of said three pieces of digital image data being data composed of 17 SBs and repetitively recorded three times without a gap left therebetween, wherein said second region comprises two pieces of digital image data recorded at eightfold speed, each of said two pieces of digital image data being data composed of 17 SBs and repetitively recorded twice without a gap left therebetween.
