发明名称 Disk drive using magnetic disk medium of discrete track recording
摘要 A magnetic disk medium of a discrete track recording (DTR) structure and a disk drive using the magnetic disk medium are disclosed. The magnetic disk medium of the DTR structure has positional-error detection servo patterns in a servo region, the positional-error detection servo patterns being formed of null servo patterns. This enables magnetic regions included in the servo region to occupy substantially 50% of the area of the servo region.
