摘要： A head (20) having very low leakage flux loss since the head is constructed with a very small elongate magnetic intercore (22), having a winding window (25) formed therein if desired, with the intercore being supported on either side by non-magnetic side support blocks (24a,24b). The side support blocks enable mounting of the head to the usual style of head block and provide the physical structure and size necessary for formation of a low wear head profile, if desired.

摘要： A magnetic head capable of preventing erosion of the magnetic metal film despite the absence of a protective film and suppressing the decrease in the playback output due to decrease in the track width while preventing cracking from being initiated and developed in the ferrite substrate. The magnetic head is prepared by forming magnetic core half blocks and by bonding the core half blocks by gap bonding using a fusion glass, each of the magnetic core half blocks being previously formed by stacking ferrite substrates 3, 5 on another ferrite substrate 4, 6, having magnetic metal films 1, 2 via glass films 10, 11 and forming track width adjustment grooves 18, 19. The glass transition temperature Tg of the glass employed for stacking the ferrite substrates is set so as to be higher than the glass yield point Tc of the fusion glass.

The magnetic head includes front gap forming surfaces which serve as the magnetic tape transportation surfaces and comprise a non-magnetic ceramic films and glass films, and rear gap forming surfaces aiming at junction at the portion reverse to the tape transportation side and comprising either the same materials at the front gap or silver-copper series alloy films. The manufacturing method forms by means of sputtering non-magnetic ceramic films at the front gap forming surfaces of the core pieces and either non-magnetic ceramic films or silver-copper series alloy films at the rear gap forming surfaces, in some cases implanting ion onto the films, and allowing the cores to abut against each other, so that the cores are subjected to heat treatment in a non-oxidizing atmospher less than or more than atmospheric pressure and at a temperature higher than the softening point of the glass and the liquid phase appearance temperature of the silver-copper series alloy.

摘要： A magnetic head having a head core (1) composed of a pair of core parts and made of a magnetic metallic material, the core parts being bonded together by a gap material composed of a low-melting point crystallized glass (3) which serves as the bonding material and layers (4) of non-magnetic material provided between the glass and the gap surfaces of the core parts. The layers of the non-magnetic material effectively prevent reaction between the low-melting-point crystallized glass and the metallic magnetic material of the core during the bonding heat treatment. In consequence,the strength of the magnetic gap, as well as dimensional precision of the same, is enhanced as compared with the conventional arrangement of the same gap size in which the bond is accomplished by a low-melting-polnt glass disposed in a groove parallel to the track, even when the bonding is executed at the same temperature. In consequence, the yield of production of magnetic heads and the reliability of the magnetic head products are remarkably improved.
