ABSTRACT:
A magnetic disk device has a magnetic recording medium in which one servo track and an array of at least one data track are formed alternately. A head portion includes a set of reading heads arranged in a radius direction of the magnetic recording medium for reading signals from the magnetic recording medium, and a controller controls a position of the head portion based on servo signals read from the servo tracks by the reading heads disposed at opposite ends of the set of reading heads.
