Abstract:
A disk recording apparatus, comprising:an actuator arm; a plurality of n heads extending from said actuator arm to write and read data to and from a first surface of a disk recording medium that is divided into 2nâˆ’1 annular groups of tracks, said plurality of n heads being spaced apart from each other in a radial direction along a single substantially radial path extending outwardly between a center of said disk and a circumference of said disk; a switching circuit alternating a data input/output path between said plurality of n heads in response to a control signal; and a controller identifying a target position on said first surface of said disk recording medium, determining which of said plurality of n heads is closer to said target position, generating said control signal to switch said data input/output path to whichever said plurality of n heads is determined to be closer to said target position.
