Abstract
A magnetic head for a recording and reproducing device includes an inductive head for recording use having an upper magnetic pole and an upper magnetic shield layer, an MR element of an MR head element for reproducing use and an MR detection head element for detecting an off-tracking. The MR detection head element and the inductive head are approximately aligned so that the MR detection head element is positioned over an adjacent track gap when the inductive head is positioned over a track. The MR detection head element detects positioning errors due to impact and vibration.
