Abstract

PURPOSE: To make the editing work efficient, by arranging four magnetic heads at interval 90° on the rotary cylinder and by equalizing azimuth angles of heads at 180° to each other and by causing azimuth angles of heads at 90° to differ from one another and by reproducing, erasing, and recording information in the prescribed order in the range of 270° by these heads.
CONSTITUTION: Four video heads CH1AWCH2B are arranged at interval 90° on rotary cylinder 2, and tape 3 is wound at ≥270°. The azimuth angle of head CH1A is equal to that of head CH1B, and the azimuth angle of CH2A is equal to that of CH2B, but azimuth angles of these pairs of heads are different from each other. CH1A starts recording from point (a); and when CH1A reaches point (d), CH2B moves 1/3P away in parallel and reaches point C. Other heads are arranged as shown in the figure. Heads are switched in the ordor of CH1A→CH2A→CH1B→ CH2B for recording and are switched in the order from CH1B with delay 180° for reproducing, and information is erased by the lower end of the next head after reproducing to secure the regular track pitch. As a result, the editing work can be efficient.
