Abstract
A magnetic recording system utilizing a magnetic recording disk. In some embodiments, one magnetic surface is utilized with an associated read/write transducer supported by a load beam. In other embodiments, the disk has a plurality of magnetic surfaces, each having an associated read/write transducer for reading and writing data in tracks in a plurality of zones and an associated load beam for supporting and positioning the respective read/write transducer at a plurality of locations above the respective surface. In one embodiment, the radial boundaries of the zones and read/write frequency for each zone are defined as a function of the number of available tracks on the recording surface. In another embodiment, the radial boundaries of the zones and read/write frequency for the zones are defined as a function of the read/write performance of the read/write transducer with respect to its associated magnetic surface. In a further embodiment, a read/write performance of the read/write transducer is determined, the recording performance of the magnetic surface is determined and the radial boundaries for each zones and the read/write frequencies for each zone are established as a funct…
