Abstract
The present invention provides a magnetic recording medium and a magnetic disk drive using the same, capable of keeping flying height and posture of the head slider constant when a discrete track medium (magnetic recording medium) includes tracks as data zones, and non-data zones (groove) formed between adjacent tracks. The width of the discrete servo field for locating the position of the track in the radial direction is set to be smaller than a width of an end of a center pad formed on a head slider of the magnetic disk drive
Claims16
A magnetic recording medium used for a magnetic disk drive, comprising:
- a plurality of data tracks;
- and
- discrete servo fields for locating respective positions of the data tracks,
- wherein a width W of the discrete servo field in a rotation radial direction of the magnetic recording medium is smaller than a width SL of a center pad end of a head slider installed in the magnetic disk drive, and equal to or larger than an interval between the data tracks.
