Abstract:
1. A method for propagating a plurality of timing marks for servo data alignment on a storage medium, the method comprising: detecting a passage of at least a portion of a first timing mark from a set of timing marks, wherein the first timing mark is located at a first radius and a first circumferential location; waiting for a delay period to expire and writing a second timing mark, wherein the second timing mark is located at a second radius and a second circumferential location; moving a recording head to a second radial location; detecting a passage of at least a portion of a third timing mark from a set of timing marks, wherein the third timing mark is located at a third radius and wherein the third timing mark is not a timing mark extension of the first timing mark; and waiting for a delay period to expire and writing a fourth timing mark, wherein the fourth timing mark is located at a fourth radius and wherein the fourth timing mark is an extension of the second timing mark.
