  • Publication number: 20100079890
    Abstract: Method and apparatus for magnetic tape recording where the magnetic tape has data and servo tracks, and address or other positioning information is encoded on the servo track. A servo track burst pattern is provided whereby certain of the bursts define a gap between the stripes of the first and second half of the burst, each burst including a certain number of the stripes. The presence of the gap in a burst indicates a first binary state, which may be defined as a digital one, and the absence of the gap defines the second binary state, which may be defined as digital value 0. Hence by defining a set of 1s and 0s, longitudinal positioning or address information is encoded on the servo track, thereby improving servo track following of a tape drive.
