| 摘要 | According to one embodiment, a head position demodulating method and a magnetic disk device switch a demodulation window such that an amplitude of a fundamental wave component of a null-type burst pattern transitions from a decreasing direction to an increasing direction along with an increase in seek speed during demodulation of the null-type burst pattern recorded on a magnetic disk. | ||

| 主权项 | 1. A head position demodulating method, comprising switching a demodulation window with respect to a null-type burst pattern recorded on a magnetic disk such that an amplitude of a fundamental wave component of the null-type burst pattern transitions from a decreasing direction to an increasing direction corresponding to seek speed during demodulation of the null-type burst pattern. | ||
