ABSTRACT:
A magnetic tape recording and reproducing apparatus has a head assembly comprising a plurality of transducing heads, and guide means arranged so that the heads are spaced apart by a distance which is great enough so that only one head is affected by a blemish or dust speck on the tape but yet gives an ability to follow tracks on the tape which are closely packed. The guide means and the heads are disposed so that when the tape is transported across the heads, the heads follow paths which are parallel to the edges of the tape and each head is in contact with a position of the tape spaced apart in the direction of movement of the tape. In one embodiment, the heads are horizontally disposed and the tape is guided over the heads at an acute angle to the horizontal. In another embodiment, the heads form part of an annulus and the tape is wound helically round a support drum.
