Abstract
PURPOSE:To attain the compression recording of 1/2, 1/4 by rotating a rotating drum at the speed of 1/2 as fast as a first drum rotating speed, controlling the travel of a tape form recording medium at a speed of 1/2 as fast as a first feed speed and providing a second mode for recording the 1/2 compressing data of digital data. CONSTITUTION:The first mode for recording the digital data by rotating the rotating drum at the first drum rotating speed and traveling the tape-like recording medium wound on the rotating drum at the first feed speed and the second mode for recording the 1/2 compressing data of the digital data by controlling the travel of the tap form recording medium at the speed of 1/2 as fast as the first feed speed are provided. The rotating speed of the rotating drum is set to 1/2 and the tape feed speed is set to 1/2, thereby, the quantity of data twice as much as before can be recorded to the first recording mode and the 1/2 compression data can be recorded. Then, this 1/2 compression is constituted of two steps, thereby, a recording of 1/4 compression can be attained.
