A magnetic head for use in an acoustic apparatus having first and second magnetic gaps provided between, and excluding, the head peak on the slidable surface of the magnetic tape and a tape departure point downstream of the running magnetic tape.

Magnetic head with reduced gap wear

A magnetic head assembly includes, a magnetic head for magnetic tape recording, a tape guide for guiding a magnetic tape, and a metal frame on which the tape guide is mounted. The magnetic head is fixed directly to the metal frame so that a material for forming the tape guide is not arranged between the magnetic head and the metal frame. The tape guide includes a tape edge positioning portion contacting with an edge of the magnetic tape so that the magnetic tape is positioned in a direction substantially perpendicular to a tape feed direction and substantially parallel to a recording surface of the magnetic tape, a recording surface guide portion for guiding the recording surface of the magnetic tape in a direction substantially perpendicular to the recording surface of the magnetic tape, and a tape urging portion which urges the magnetic tape toward the tape edge positioning portion so that the magnetic tape is positioned along the tape edge positioning portion. Further an angle between the recording surface guide portion and an imaginary plane tangent to the tape urging portion at a place on which another edge of the magnetic tape contacts with the tape urging portion is increased continuously in a direction extending from the edge of the magnetic tape positioned by the tape edge positioning portion toward the another edge of the magnetic tape urged by the tape urging portion.
