摘要:
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.
摘要(中):
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。
