Abstract
A method of writing data using more than one write head to write to more than one storage media platter surface of a storage device, where one actuator in the storage device controls positions of all of the write heads, includes controlling the position of one of the write heads to a selected radial track location, writing simultaneously to storage media of the storage device at the selected radial track location using a plurality of the write heads, and, during the writing at the selected radial track location, reading servo data using respective read heads associated with each respective one of the plurality of write heads and recording the radial position of the respective heads for the selected radial track location. During reading, the recorded head position for the track of the platter surface to be read is determined, and the read head is served to the recorded head position.
