Magnetic recording apparatus with a head error detection circuit

Abstract

The present invention provides a magnetic recording apparatus for recording/reproducing a data with a comparatively high density. The magnetic recording apparatus comprises: a magnetic recording medium having a data area and a spare area; a head for data write in the data area with a predetermined recording frequency; a head error detection circuit for detecting a head error during a data write; and a controller that operates as follows. When an error is detected by the head error detection circuit, a data write is carried out in the spare area and if this does not cause an error, it is decided that the head is normal.
