摘要： A magnetic head assembly that lessens undesired or harmful vibration is provided. A gimbal 2 of a magnetic head assembly 1 has an outskirt part 4, an intermediate part 7, and an inland part 10. The intermediate part 7 is arranged inside the outskirt part 4 with first aperture segments 5a and 5b therebetween, and is connected to the outskirt part 4 via first bridges 6a and 6b. The inland part 10 is arranged inside the intermediate part 7 and connected thereto via second bridges 9a and 9b and second damping parts 12a and 12b. The second bridges 9a and 9b and the second damping parts 12a and 12b act so as to modify the resonant frequency of the inland part 10. Additional damping parts may be provided.

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.
摘要翻译：滑块4的孔5的第二内壁30b和第四内壁30d包括第二和第四突起31b和31d，并且第一内壁30a不具有突起并且倾斜于垂直表面50 以一个角度θ。第二突起31b和第四突起31d的升高部分形成在半径曲率部分51中。由于在将前芯8插入孔5中时，前芯8的侧部8e邻接于第一内壁30a在一条线处，前芯8通过前芯8的推动力在A方向上精确地定位，并且通过将临时粘合剂施加到靠近B部分和靠近第四突起31d的位置。在模制滑块4之后提取模具时，避免了对半径曲率部分51的内部应力的集中，并且控制缺陷和破裂等缺陷的产生以提高可靠性，减少缺陷产品的比例，提高生产率和实现成本降低。
