Abstract

Extensive use of a magnetic head with magnetic tape causes the edges of the tape to wear small ledges in the surface of the head. Since the width of tape varies slightly, the tape rides up on the ledges causing the loss of information recorded in the outermost tracks.

Channeled Magnetic Head

Extensive use of a magnetic head with magnetic tape causes the edges of the tape to wear small ledges in the surface of the head. Since the width of tape varies slightly, the tape rides up on the ledges causing the loss of information recorded in the outermost tracks.

This situation is remedied by cutting grooves in the head surface adjacent to the outside tracks. No matter what the variation is in tape width, the edges always stay within the grooved area. This prevents the formation of ledges by the tape edges and thus provides constant contact of the tape with the entire head surface.
