Abstract:
1. Apparatus for storing data in the form of marks, said marks being written and/or read by an array of probes, comprising: a plurality of data fields, each field comprising an area of the storage medium which, in use, is scanned for reading and/or writing by an associated one of the array of probes; wherein the data fields include operational data fields having operational data for operating said scanning stored therein; wherein the operational data fields are arranged in a plurality of clusters, each cluster comprising a plurality of adjacent operational data fields having operational data stored therein, wherein each cluster comprises two timing data fields, having a clock mark pattern and calibration data respectively stored therein, for adjusting a clock used to read/write data, at least one of which comprises a servo data field having servo data stored therein for determining positioning of the probe array during scanning, and at least one of which comprises a timing data field having timing data stored therein for determining timing of read and/or write pulses during scanning wherein the apparatus is a data storage medium.
