Abstract
A principle embodiment teaches a strobing method and associated apparatus for magnetic recording/detecting systems especially adapted for use in high performance, high capacity, low cost disk drives wherein there is provided strobing means adapted to produce a chain of timing pulses and to distribute them relatively uniformly across a data cell of variable length and so provide a sampling means for such cells.

In a magnetic recording system including a prescribed read/write arrangement involving digital data signals, the combination therewith of an improved strobe means adapted to generate a selectable number of timing pulses as a "strobe chain" and to adjustably and uniformly distribute them across a "data cell" of variable length, and to provide timing-sampling means adapted to accommodate such "data cells", whereby to facilitate improved sub-cell sampling and data detection.
A magnetic recording system including an improved read/write arrangement operating according to given parameters and adapted to produce digital data signals in terms of a prescribed normalized "data cell" length and characterized by pulse stretching means adapted to adjust the length/duration of said data cells in response to prescribed changes in said system parameters, together with timing-sampling means adapted to accommodate such variable-length "data cells".
