Latest Patents

Thambirajah holds a patent for a "Method for writing servo patterns and disk drive including a controller for writing servo patterns according to the method." This method involves writing servo patterns onto a disk of a disk drive. It includes providing a variety of different drive currents for an actuator while pushing the actuator into a crash stop, which defines the swing range of the actuator. The method also entails performing a write operation for at least one of the different drive currents to write multiple servo pattern tracks, which consist of separate servo pattern sectors. Additionally, the method gradually changes the drive current while pushing the actuator into the crash stop, allowing the read element to search for a servo pattern track at a different radial position from the write element. Ultimately, the read element is positioned at one of the servo pattern tracks.
