Abstract:
A disk drive is disclosed wherein during a write operation a write fly height actuator is configured with a pre-heat value and a read fly height actuator is configured with a read value. When the head is over a target data sector, the write fly height actuator is configured with a first write value and the read fly height actuator is configured with a second write value, and data is written to the target data sector. When the head transitions from writing data to the target data sector to reading a servo sector, the write fly height actuator is configured with the pre-heat value and the read fly height actuator is configured with a read value. After reading the servo sector, the write fly height actuator is configured with the first write value and the read fly height actuator is configured with the second write value.
