Abstract
A single end input type high frequency amplifier of the present invention decreases noise superposed on a power supply of a pre-amplifier in a read amplifier which amplifies a signal from MR head. The single end input type high frequency amplifier includes a transistor connected to an input side terminal of a differential input amplifier. A single end type resistor is connected to the transistor and a loop amplifier is connected to the single end type resistor to feedback a difference voltage between a reference side terminal and an input side terminal of the differential input amplifier.
