ABSTRACT:
A method of forming servo data, and a self-servo write method using the same, the method including partial response maximum likelihood (PRML)-coding servo data into m bits in n-bit units; multiplying each bit of the PRML-coded result by an o multiple; and converting a bitsream obtained in the multiplying to ((m
)−p) bits in m
-bit units.
