摘要： A magnetic head assembly with dual parallelogram supporting structure device and method of making the same has a single or multiple track magnetic stripe read head transducer mounted to a support structure by a dual parallelogram spring structure. This dual spring structure allows the head to move perpendicularly and rotationally to the magnetic stripe while preventing the head from rotating in the y direction, namely, preventing lateral movement. The novel magnetic head assembly is produced using a rapid and accurate assembly without the use of mounting screws in single and multiple track configurations. The unique spring also reduces wear on the magnetic heads which increases the functional life of the unit. The simple construction allows inexpensive manufacture of the magnetic head assembly, yet the durability of available manufacturing materials and the structure of the spring provide the magnetic head assembly with a long useful life, requiring little or no maintenance expense or upkeep.
摘要翻译：具有双平行四边形支撑结构装置的磁头组件及其制造方法具有通过双平行四边形弹簧结构安装到支撑结构的单轨道或多轨磁条读头传感器。这种双弹簧结构允许磁头垂直和旋转地移动到磁条，同时防止磁头在y方向旋转，即防止横向移动。新型磁头组件是使用快速准确的组件生产的，而不需要使用单轨道和多轨道配置中的安装螺钉。独特的弹簧也减少了磁头上的磨损，从而增加了机组的使用寿命。简单的结构允许廉价地制造磁头组件，然而可用的制造材料的耐用性和弹簧的结构为磁头组件提供了长的使用寿命，需要很少或不需要维护费用或维护。

摘要： An audio/control head for used in a Video Cassette Recorder or the like has a core holder 11 arranged to include positioning portions 24 and 25 for determining the pitch length P1 and pressing tabs 23 having an elasticity for pressing inwardly cores members 15 and 17 against the positioning portions 24 and 25 from the outer side. As the cores members 15 and 17 are held directly on the positioning portions 24 and 25, they are inwardly pressed by the pressing tabs 23. Then, the core pitch p1 is precisely determined between the audio core and the control core without using a particular jig during the assembly. The overall number of jigs required for mounting the cores to the core holder can be reduced. Also, the core pitch P1 can be improved in the accuracy and the characteristics of the head will be consistent.

摘要： The second inner wall 30b and the fourth inner wall 30d of the hole 5 of the slider 4 comprises the second and the fourth projections 31b and 31d, and the first inner wall 30a is not provided with a projection and is inclined to the vertical surface 50 at an angle &thgr;. The raising portions of the second projection 31b and the fourth projection 31d is made in the radius curvature portion 51. Since, at the time of insertion of the front core 8 into the hole 5, side portion 8e of the front core 8 abuts to the first inner wall 30a at one line, the front core 8 is positioned precisely by the pushing force of the front core 8 in the A direction, and by application of a provisional adhesive to near B portion and near fourth projection 31d. At the time of extracting of the die after molding the slider 4, the concentration of the internal stress to the radius curvature portion 51 is avoided, and the generation of the defects such as lacking and cracking are controlled to increase the reliability, reduce the defective rate of the product, to increase the productivity and to realize the cost down.

摘要： A magnetic head exhibits a good traceability without damaging itself or a magnetic disk. The magnetic head includes a slider, and the slider includes a plurality of magnetic cores and an outrigger having a plurality of substantially rectangular slots. The magnetic cores have respective operating gaps for a standard recording density and a high recording density and are inserted into the respective substantially rectangular slots. One magnetic core for a high recording density having a spacer superposed thereon is inserted in one of the slots in such a manner as to touch a wall of the slot. The slider includes a rail surface which has a groove passing longitudinally through the spacer substantially at the center of its thickness and reaching both lengthwise ends of the slider, and the rail surface slides against a magnetic recording medium.
