摘要
A disk storage system having servo data stored thereon for accurate head position control over a magnetic or other storage medium. The servo data is seamless and untrimmed and consists of a primary servo burst set (AB burst) that defines the desired tract pitch for the surface. Multiple secondary servo burst sets (e.g., CD burst and EF burst) are written at the desired track pitch but radially offset from the primary burst set. The servo data is written in multiple servo sectors around the surface of the medium. From the servo data, PES (position error signals) are generated for providing linear position sensitivity information to the head position control logic. The resulting PES is more linear for smaller head sizes.
