    • Sliding noise characteristics can be considerably improved without degrading electromagnetic conversion characteristics and abrasion resistance characteristics in a recording/reproducing operation. A depth (H) of a contact width regulating groove (21) is set to be smaller than a contact width (W) of a magnetic recording medium sliding surface (a), and is set to a predetermined value of 25 mu m or more and 45 mu m or less. A depth (H) of the contact regulating groove is set to a predetermined value of 37+/-12 mu m, the contact width (W) on the magnetic recording medium sliding surface (a) is set to a predetermined value of 55+/-6 mu m, and a value (R) of a corner portion (51a) of the contact width regulating groove is set to a predetermined value of 16 mu m or less.
    • 在记录/再现操作中,滑动噪声特性可以显着提高而不降低电磁转换特性和耐磨损特性。 接触宽度调整槽(21)的深度(H)被设定为小于磁记录介质滑动面(a)的接触宽度(W),并被设定为25μm或更大的预定值 和45微米或更小。 将接触限制槽的深度(H)设定为37±12μm的规定值,将磁记录介质滑动面(a)的接触宽度(W)设定为规定值55+ /-6μm,接触宽度调整槽的角部(51a)的值(R)被设定为16μm或更小的预定值。

    • Provided is a vertical writing type magnetic head including a substrate, a bottom pole formed on the substrate, and a top pole aligned with and spaced a predetermined distance apart from the bottom pole, wherein the bottom pole has a narrower width than the top pole. The magnetic write head is constructed such that the width of a bottom pole is narrower than that of a top pole, thereby reducing extension of a magnetic field at sides of a top pole and effectively preventing erasure of information of an adjacent track due to the bottom pole overlapping the adjacent track when there is a constructional skew in a hard disk drive.
    • 提供一种垂直写入型磁头,其包括基板,在基板上形成的底部磁极,以及与底部磁极隔开预定距离对齐的顶部磁极,其中底部磁极具有比顶部磁极更窄的宽度。 磁写入头被构造成使得底部磁极的宽度比顶部磁极的宽度窄,由此减小顶部磁极侧的磁场的扩展并且有效地防止由于底部而导致的相邻磁道的信息的擦除 当硬盘驱动器中存在结构歪斜时,极与相邻轨道重叠。
