Title: Magnetic head driving circuit
Inventor: KODA TOMOHIRO
IPC: G11B5/02
Filed: 2001-04-19
Abstract: PROBLEM TO BE SOLVED: To suppress the power consumption by the simple constitution when the drive is changed over to the low frequency driving. SOLUTION: Switching elements Q2, Q4, Q5, Q6 consist of the enhancement type N-channel FETs, and switching elements Q1, Q3 consist of the enhancement type P-channel FETs. When the high frequency driving current is supplied to a coil L, each group of the switching elements Q1, Q4 and the switching elements Q2, Q3 is alternately turned on/off. Meanwhile, when the low frequency driving current is supplied to the coil L, each group of the switching elements Q4, Q5 and the switching elements Q2, Q6 is alternately turned on/off, and since an impedance of the coil L is low and a voltage between both ends is low in this case, the power consumption is reduced by lowering the power source voltage. Since the switching elements Q5, Q6 are the N-channel FETs, the application of the negative gate voltage is unnecessary even though the power source voltage is lowered.
