Rotary drum and magnetic tape recording/reproducing apparatus using the same

Abstract

There is provided a rotary drum which is capable of increasing recording density of a magnetic tape by changing tape/head relative speed and by solving problems which occur in increasing the tape/head relative speed. The inventive rotary drum includes a pair of recording heads having different azimuth angles and disposed separately with 180° of central angle and a second recording head disposed at the same position in the circumferential direction with one recording head among the pair of recording heads while separating by 5.5 μm in the direction of height of the rotary drum and having a different azimuth angle from the one recording head. A first mode is created by the pair of recording heads separated by 180° of central angle and a second mode is created by the two recording heads at the same position in the circumferential position.
