Abstract: An electrical lap guide (ELG) system and method are disclosed for use in lapping a bar (10) of magnetic transducer carrying sliders to a desired transducer height. A first ELG (ELG1) contained within the bar has at least two first ELG resistive elements (R11, R12). A second ELG (ELG2) contained within the bar has at least two second ELG resistive elements (R21, R23). A first of the at least two first ELG resistive elements is electrically coupled to a first of the at least two second ELG resistive elements to thereby reduce a total number of leads needed between a data acquisition unit (100) and the bar (10) during lapping. The reduction in required data acquisition unit (100) leads (L) allows more ELGs to be included on each bar (10) in order to more accurately control the lapping process

Abstract: The general concept of the invention is to coat, at least, the trailing pole face of a pair of ferrite pole faces (26), which define a transducer gap, with high-saturation material (30) such as Sendust. By so structuring a head with a gap liner, not only is the critical part of its gap defined by material having a high saturation magnetization -- and thus such head will no be easily subject to critical pole tip saturation of its trailing pole face -- but also (1) the long-wearing ferrite will desirably constitute the principal head part that slidingly coacts with a recording medium, (2) no high reluctance glue line will exist between a core and its tips, and (3) the signal flux will enter the gap region uniformly over the surface of the gap, thereby providing enhanced high frequency efficiency.

Abstract translation: 本发明的一般概念是至少涂覆一对铁氧体磁极面（26）的尾极面，这些铁氧体磁极面（26）与高饱和材料（30）如Sendust形成换能器间隙。 通过如此构造具有间隙衬垫的头部，不仅由具有高饱和磁化强度的材料限定其间隙的关键部分，因此这样的头部不会容易受到其后极面的临界极尖饱和， 而且（1）长时间磨损的铁氧体将理想地构成与记录介质滑动共同作用的主要头部，（2）芯与其尖端之间不会存在高磁阻线，（3）信号通量将 在间隙的表面上均匀地进入间隙区域，从而提供增强的高频效率。

Abstract: A sealing glass for the front gap side of a magnetic head comprising 13 to 17 wt % of SiO2, 5 to 6.8 wt % of B2O3, 70 to 77 wt % of PbO, 0.1 to 5 wt % of at least one of Al2O3 and ZnO, and 0.1 to 3 wt % of at least one of Na2O and K2O; and a sealing glass for the back gap side of a magnetic head comprising 3 to 9 wt % of SiO2, 11 to 17 wt % of B2O3, 66 to 77 wt % of PbO and 3 to 15 wt % of at least one of Al2O3 and ZnO. These types of sealing glass can be used for providing a high performance magnetic head having high strength in high yield. The conventional types of sealing glass for a magnetic head have compositions which render the sealing glass to be easy to crystallize and be poor in strength, and thus have a problem that they are prone to suffer the occurrence of cracking by an impact when a head chip is manufactured by cutting and grinding, in a recent production process wherein a magnetic head having a narrow track and a narrow gap which corresponds to a high density recording is manufactured with high accuracy.

Abstract: A thin film magnetic recording head is fabricated by forming a substrate from opposing ferrite blocks which have a ceramic member (14) bonded between them. This structure is then diced to form a plurality of columns, wherein each column has a ferrite/ceramic combination (16A,14; 16B,14; 16C,14; 16D;14; 16E,14). Each column represents a single channel in the completed head. A block of ceramic is then cut to match the columned structure and the two are bonded together. The bonded structure is then cut or ground until a head is formed, having ceramic disposed between each channel. A ferrite back-gap is then added to each channel, minimizing the reluctance of the flux path. The thin film is patterned on the head to optimize various channel configurations.

Abstract: A longitudinal recording head (50, 56, 60) for use with magnetic recording media includes a non-uniform gap (54, 59, 64) between first (51, 57, 61) and second magnetic (52, 58, 62) poles which focuses magnetic flux onto a small area of the magnetic recording medium. The non-uniform gap is preferably in the form of a cavity that is contoured to produce the desired flux pattern. Longitudinal recording heads incorporating the non-uniform gap are capable of improved recording densities.

Abstract: A thin film magnetic recording head (5) utilizing a timing based servo pattern is fabricated using a focused ion beam (FIB). The recording head is fabricated by sputtering a magnetically permeable thin film (16) onto a substrate (12, 14). A gap pattern, preferably a timing based pattern, is defined on the thin film and the FIB cuts a gap (30) through the thin film based on that pattern. Once completed, the recording head is used to write a servo track onto magnetic tape. The timing based servo track then allows for the precise alignment of data read heads based on the positional information obtained by a servo read head which scans the continuously variable servo track.
