摘要： Servo patterns for patterned media (1201,1202,1203,1208). The servo pattern includes specification of cylinder/track ID with and without a Gray code. The servo pattern space is minimized by the optimum usage of the islands (1204,1209). This is achieved by island allocation rules to take advantage of non-magnetic island. The island allocation also provides for easier lift-off. Logic is used to encode and decode the Gray code. Further, the Gray code is designed to stabilize the magnetic island (1204,1207)/ non-magnetic island (1205,1209) ratio to allow for easier manufacture.

摘要翻译： 图案介质的伺服图案（1201,1202,1203,1208）。 伺服模式包括具有和不具有格雷码的气缸/轨道ID的规格。 通过岛屿的最佳使用，使伺服图案空间最小化（1204,1209）。 这是通过岛屿分配规则实现的，以利用非磁性岛屿。 岛屿分配也提供了更轻松的起飞。 逻辑用于对格雷码进行编码和解码。 此外，格雷码被设计成稳定磁岛（1204,1207）/非磁岛（1205,1209）的比例，以便于制造更容易。
