Abstract
A method of writing data on a disk includes the step of writing a first subset of data on a disk such that an amount of write power to write the first subset of data is adjusted in a closed-loop operation. A write-power signal representing the amount of write power to write the first subset of data is measured. After a write interruption, such as from a buffer under-run, a second subset of the data is written on the disk in an open-loop operation using the measured write power, such that the second subset of data is adjacent to the first subset of data.
