Multichannel magnetic head |
摘要 |
A multichannel magnetic recording/reproducing head for which the amount of waving of the tape is significantly reduced and contamination of the recording/reproducing gaps of the head by dust or the like is substantially eliminated. A plurality of parallel grooves are formed on a tape-contact surface of the head, inclined with respect to a running direction of the magnetic tape and provided at least at a tape-entrance side of the surface. The inclination of the grooves is within an angular range of 1 to 30 degrees with respect to the tape running direction, and the depth of the grooves is within a range of 0.1 to 20 microns.
