摘要： A magnetic head having a pair of nonmagnetic core base bodies coupled to each other in such a manner that amorphous magnetic alloy films are applied to their abutment surfaces and a gap layer is interposed in a magnetic gap of the head, the films applied to the bodies being made abut against each other at their end edge surfaces each of which has a width larger than its film thickness, and at least one of the bodies having a coil winding groove formed at a portion at which the bodies are coupled to each other. Surface layer portions of each of the bodies, with which a magnetic tape comes into contact, are removed along a direction in which the magnetic tape moves, to a depth which is substantially the same as the depth of the gap while leaving a widthwise portion, which is the same as the track width defined by the width of contact between the two end edge surfaces of the films, at the widthwise center of the bodies, two recesses which are formed by removing the surface layer portions being filled with 2MgO--SiO.sub.2 or MgO--SiO.sub.2, and another amorphous magnetic alloy film is applied to the inner surface of the coil winding groove which defines a coil winding aperture and the latter film is integrally continued to the former films.

摘要： An arrangement is designed to achieve satisfactory tape contact by setting a specific ratio for the width of a drum window and the head length of a double azimuth head. The head length L is defined as the distance from the front end of the preceding head to the back end of the succeeding head. When the drum window width W is defined as the distance of the drum window in the rotary direction, the preceding head and the succeeding head are arranged within the drum window to satisfy the relation 1.15 L.ltoreq.W.ltoreq.1.28 L. When the space S1 is defined as the distance from the front end of the preceding head to the front end of the drum window, and the space S2 is defined as the distance from the back end of the succeeding head to the back end of the drum window, the preceding head and the succeeding head are arranged within the drum window to satisfy the relation 0.075 L.ltoreq.S1.ltoreq.0.14 L and 0.075 L.ltoreq.S2.ltoreq.0.14 L. According to this arrangement, the magnetic tape intrudes preferably into the space between the double azimuth head and the drum window. The magnetic tape envelopes and contacts the head surface, so that the tendency for a spacing to occur between the head and the tape is suppressed. The reproducing output is increased and stabilized in this way.

摘要： The present invention provides a magnetic recording and reproducing apparatus, a magnetic recording and reproducing method, and a thin film magnetic head that enable a good contact between elements and a recording medium with a reduced track pitch even if the number of head channels is increased, thereby realizing high recording density and high transfer rate.At least one multitrack write head having N (N is an integer of 2 or more) write elements arranged along a track width direction in an integral fashion and at least one multitrack read head having L (L is an integer equal to or more than N) read elements arranged along the track width direction in an integral fashion are formed on the rotary drum. The multitrack write head writes signals to a group of N tracks aligned parallel on the magnetic tape during one rotation of the rotary drum, and the multitrack read head reads the group of N signal tracks by the use of any one of the L read elements.
