Abstract:
A magnetic disc device according to an embodiment has a head, a position detector, and a filter unit. The position detector detects position information of the head on the basis of servo information. The filter unit performs filtering of an estimated frequency estimated by a quadratic adaptive digital filter that performs self-adaptation for a transfer function on the basis of positional difference information between position information and target position information of the head and adjusts all filter coefficients included in the transfer function on the basis of the estimated frequency.

Claim (Index 4):
The magnetic disc device according to  claim 3 , wherein the memory unit stores a coefficient of a quadratic function that calculates the filter coefficients P, Q, R, E, and F when the estimated frequency is substituted.
