Abstract

PURPOSE:To enable to use a large substrate, and to facilitate to handle a rotary head drum at the time of assembling work, and to improve work efficiency by installing one each of a magnetic head or a video signal and a magnetic head for a sound signal on the same substrate in parallel, and arranging the plural substrates at the outer circumference of the rotary drum at equal angles. CONSTITUTION:The magnetic heads 9a-9d for the video signal and the magnetic heads 11a-11d for the sound signal of the rotary head drum C are installed in parallel small gap apart on the same substrates 12a-12d respectively. The substrates 12a-12d are arranged on the outer circumference of the rotary drum 13 at intervals of 90 deg.. The sizes H of fixing level differences between the heads 11a-11d and the heads 9a-9d on the substrates 12a-12d, and the respective pitch sizes of a video pattern and a sound record pattern, recorded on a magnetic tape 1, are made to be prescribed values. Then, the assembling work of the drum C is made efficient without making the substrates 12a-12d to support the heads 9a-9d, 11a-11d small.
