ABSTRACT:
Disclosed is a magnetic recording circuit for magnetically recording data on a magnetic record medium with a high density. This magnetic recording circuit comprises a magnetic head and a drive circuit for the magnetic head. This drive circuit includes a variable damping circuit for variably setting a damping factor, of the magnetic head, for controlling a damping characteristic of a record current of the magnetic head. The magnetic recording circuit further comprises a frequency detection circuit for detecting a frequency of the data given to the drive circuit and selecting the damping factor of the variable damping circuit on the detected frequency. The damping factor corresponding to the frequency of the data to be written is set, and hence a resolution required is obtained in a high record frequency range, while a shooting quantity can be reduced in a low record frequency range.
