Abstract:
1. A magnetic head which is mounted on a rotary drum capable of allowing a tape magnetic recording medium to run thereon and moves with the rotation of said rotary drum, so as to perform recording on said tape magnetic recording medium or reproducing from said tape magnetic recording medium, said magnetic head comprising: a surface for facing said tape magnetic recording medium and for performing hydrodynamic interference with said tape magnetic recording medium while moving by said rotation; a recording/reproducing portion for producing magnetic interference with said tape magnetic recording medium in a non-contact state, wherein the entire surface for facing said tape magnetic recording medium is a smooth flat surface placed within a cylindrical drum surface, wherein a head gap is placed in a range where a magnetic tape is close to a minimum distance capable of producing mutual magnetic recording and reproducing, and said recording/reproducing portion is placed outside an area where said tape magnetic recording medium contacts said surface by the hydrodynamic interference and is provided so as to be able to perform at least either recording or reproducing by the magnetic interference with said tape magnetic recording medium in a non-contact state.
