Abstract
Official abstract text for this publication.
A bit patterned media (BPM) encoded recordable medium includes a servo control field including servo bits. Each servo bit is represented by a servo bit pattern of dots and gaps on the recordable medium. In the servo bit patterns, substantially no two dots are placed immediately next to one another, and substantially all servo bit patterns start with a gap and/or substantially all servo bit patterns end with a gap.
First claim
Opening claim text (preview).
What is claimed is: 1. A device, comprising: a servo control field comprising a plurality of servo bits, wherein each servo bit is represented by a servo bit pattern of dots and non-magnetic gaps on the device in which substantially no two dots are placed immediately next to one another, and wherein substantially all servo bit patterns start with a non-magnetic gap and/or substantially all servo bit patterns end with a non-magnetic gap. 2. The device of clai…
