Abstract:
1. A method for optimizing data record quality on a disk for a given pair of read and write heads, in which the write head is bigger than the read head, by adaptively varying the linear density and track density of overlapping tracks of data recorded to achieve a target storage capacity, comprising: selecting a target storage capacity; selecting a radial direction to write data tracks; determining a write width for the write head; determining a read width for the read head; determining a pairing of a linear density and an offset distance to optimize data record quality for the combination of said write head, said read head, and said target storage capacity, wherein said offset distance is less than said write width but greater than said read width; writing a first data track on a disk at said linear density with said write head; offsetting said write head in said selected radial direction by said selected offset distance; storing said offset distance; writing a new data track onto said disk with said write head at said linear density; and repeating said offsetting of said write head, said storing said offset distance, and said writing a new data track onto said disk with said write head at said linear density until all desired data has been written into a cluster.
