Abstract

Shown is a magnetic head oriented 90 degrees to the normal method of reading digital magnetization. Head 10 is oriented over magnetic tape 12 such that its read gap 14 is aligned with the magnetization in track 16. In normal magnetic transducing, the read gap of the head is oriented so that the magnetization of the track is across the read gap. As shown, the head is 90 degrees skewed from the normal position, and the magnetization of the track 16 is aligned with the gap 14.

Reading Magnetization With 90 Degree Skewed Head

Shown is a magnetic head oriented 90 degrees to the normal method of reading digital magnetization. Head 10 is oriented over magnetic tape 12 such that its read gap 14 is aligned with the magnetization in track 16. In normal magnetic transducing, the read gap of the head is oriented so that the magnetization of the track is across the read gap. As shown, the head is 90 degrees skewed from the normal position, and the magnetization of the track 16 is aligned with the gap 14.

There is, of course, a considerable reduction in signal read by the head 10, but the signal is useable. The advantage of orienting the head in this direction is that the gap or effective gap size is very much smaller than the width of the track. By reducing the effective gap size in this manner, the track 16 may be made much smaller in width. Alternatively, if the track width remains the same, the problem of guiding the head relative to the track is greatly reduced.
