Methods of demodulating a servo position error signal on patterned media |
| 摘要 |
A system includes, in at least one aspect, a storage device including patterned media and a head; and a read channel configured to: receive a DC readback signal from the head, the DC readback signal including position error signal (PES) information associated with a position of the head with respect to the patterned media, and determine the position of the head with respect to the patterned media based on a result of summing the DC components of the PES information. |

1. A system comprising:
a storage device including patterned media and a head; and a read channel configured to:
receive a direct current (DC) readback signal from the head, the DC readback signal including position error signal (PES) information associated with a position of the head with respect to the patterned media, anddetermine the position of the head with respect to the patterned media based on a result of summing DC components of the PES information. |
