気記録再生装置の記録補償回路。[Claim for Utility Model Registration] A feedback circuit connected to an amplifier for recording compensation is composed of a plurality of impedance elements, and these impedance elements can be used to control multiple running speed modes of the magnetic tape and magnetic tapes with different recording densities. In a recording compensation circuit of a magnetic recording/reproducing device, the compensation amount and peaking frequency are selected according to the tape used and the speed mode by switching and selectively connecting the mutual combination with the tape and the speed mode. 1. A recording compensation circuit for a magnetic recording/reproducing device, characterized in that the configuration of a feedback circuit is simplified by setting the frequencies to the same frequency and commonly using an impedance element that determines the frequency.
