Abstract

A rotating head having a pair of recording gaps at a substantial angle with respect to each other is used to record and read closely adjacent diagonal tracks on a wide tape. The bits recorded in each track are at an angle to those recorded in immediately adjacent tracks so that crosstalk is minimized, no intertrack spacing is needed and recording is at the maximum density.

Herringbone Magnetic Recording With A Rotating Head

A rotating head having a pair of recording gaps at a substantial angle with respect to each other is used to record and read closely adjacent diagonal tracks on a wide tape. The bits recorded in each track are at an angle to those recorded in immediately adjacent tracks so that crosstalk is minimized, no intertrack spacing is needed and recording is at the maximum density.

The wide tape is wrapped around a pair of aligned stationary mandrels 1 having a head 2 rotating between them. The magnetic case of the head 2 has two gaps 3 formed by a single cut at an angle to the axis of rotation. With the head rotating at high speed and the tape 4 moving slowly, the gaps are alternately effective to record adjacent lines of angularly disposed marks in a herringbone pattern as is indicated on the tape.
