Abstract

PURPOSE:To prevent gaps between two combination heads from being clogged by providing a helical scan type rotary cylinder with a base member where the combination heads are fitted so as to prevent magnetic powder which is accumulated between the heads from sticking by blowing out air through the rotation of the cylinder. CONSTITUTION:The rotary magnetic head which has two couples of combination heads 3-A and 3-A; and 3-B and 3-B' is fitted to the helical scan type rotary cylinder 1, and the head fitting member 2 is provided so that when the cylinder 1 is rotated as shown by an arrow 11, a flow 12 of air extend to the gaps between the two couples of combination heads 3-A and 3-A' and 3-B and 3-B'. Consequently, magnetic powder, dust, etc., from a magnetic tape 10 are prevented between the tape 10 and heads, thereby performing excellent recording and reproduction.

る。Embodiment An embodiment of the present invention is shown in FIGS. 1 to 4. In these figures, a rotating cylinder 1 rotates and a magnetic head 3 comes into contact with a magnetic tape 10 during recording and reproduction. According to this embodiment, as shown in FIG. 4, air flow 12 is obtained by attaching the head in the cylinder rotation direction 11 by making the base 2 into a predetermined shape so that air is expelled between the combination heads. It will be done. By expelling air between the combination heads, it is possible to minimize the adhesion of magnetic powder between the combination heads, where magnetic powder is most likely to adhere.
