Abstract

A data format defining a data field having an embedded reading-address subfield and an offset writing-address header allows a transducer having separate read and write elements separated by a gap to perform read and write operations. When reading from the disc, the read element is positioned adjacent the data fields stored on a track. As the data fields pass the read element, the data field addresses stored in the embedded reading-address subfields are compared to a target address. If a match is found, the user data contained in a user data subfield of the matched data field is provided to a controller. When writing to the disc, the read element is positioned adjacent the writing-address headers. The addresses stored in the writing address headers are read and compared to the target address. If a match is found, the user data provided by the controller is written to the user data subfield of the data field associated with the matched writing-address header, and the address of the data field is rewritten to the embedded reading-address subfield of the data field. The data field is offset from the writing-address headers by a magnitude determined by the gap and skew angle.
