摘要： A head gimbal assembly includes a magnetic head slider provided with a recording head element that applies a recording magnetic field to a magnetic recording medium and a suspension that supports the magnetic head slider. The magnetic head slider further includes a microwave radiation element that radiates a microwave magnetic field from a microwave excitation current that is supplied from a microwave generating circuit, and that applies the microwave magnetic field to the magnetic recording medium when the recording head element applies the recording magnetic field to the magnetic recording medium. The suspension includes a microwave transmission line that transmits the microwave excitation current, and the microwave transmission line is provided with a matching circuit to achieve impedance matching with the microwave radiation element.

摘要： The burst pattern shape in a discrete medium is set to a shape (truncated quadrangular pyramid shape) having substantially trapezoidal shapes in a track width direction and in a track circumferential direction, respectively, and a predetermined relationship is satisfied among W1, W2, Tp, and Wr where W1 represents an upper side corresponding to the surface of a convex magnetic recording layer and W2 a lower side corresponding to the lower surface of the convex magnetic recording layer in the trapezoidal shape in the track width direction, Tp represents a data track pitch of a data information recording portion, and Wr represents a read width of a magnetic head. Therefore, the burst pattern shape makes it possible to largely reduce a production load in processing and still to obtain an accurate position error signal.
