摘要:
A magnetic disc has a magnetic recording area on or from which the information may be recorded or reproduced by a recording head loaded on a slider. The magnetic recording area has a data area including a recording track as a crest and a guard band as a valley, and a servo area having servo marks as crests and valleys. A CSS area for contact-start-stop (CSS) with the slider is made up of CSS data areas radially consecutive to the data areas and CSS servo areas radially consecutive to the servo areas. The entire surfaces of the CSS servo areas may be planarized at the same height level as the recording tracks. The CSS servo areas are provided with the same pattern of crests and valleys similar to that of the data areas. This suppresses generation of powder debris during CSS while optimizing the amount of float of the slider and the floating posture in the CSS area.
