Abstract
Data are written as transitions on plural tracks of a magnetic disc by a transducer which travels along an arcuate curve formed by an arm turning about an axis beyond the disc periphery. Transition positions are defined by the phase thereof relative to that of a reference indicator on a track of the disc. To align the transitions along a predetermined arcuate curve, a reference transition having a reference phase is written onto a given track. Other transitions of the second curve are written with a phase shift relative to the reference phase.
