A method of performing data/information recording and retrieval utilizing
a multilevel patterned magnetic medium, comprises: (a) providing a
magnetic recording system including a read/write head and a multilevel
patterned magnetic recording medium including a plurality of spaced apart
elements each comprising a stacked plurality n of magnetic recording
cells with different magnetic properties and magnetically decoupled from
overlying and/or underlying cells; (b) providing relative movement
between the write head and magnetic recording medium; and; (c) writing to
the medium by supplying the write head with a modulated write current
comprising a plurality n of pulses of different magnitudes while the head
moves past each element, thereby applying n different magnetic field
strengths to each element, the write current including a first pulse of
magnitude sufficient to write to a first cell of each element having a
highest magnetic coercivity of said cells, and n-1 succeeding pulses of
progressively smaller magnitude for sequentially writing to the remaining
n-1 lower magnetic coercivity cells of each element but of insufficient
magnitude to write to progressively higher magnetic coercivity cells;
whereby the writing occurs in a single pass of the write head past each
element.
