ABSTRACT:
A vertical magnetic recording and reproducing head includes a magnetic sensing element for sensing a magnetized pattern recorded in a recording medium which serves as a main magnetic electrode in the reproduction mode, a bias section for biasing the magnetic sensing element, and a main magnetic pole which is disposed adjacent to said magnetic sensing element. The main magnetic pole includes a magnetic member serving as the main magnetic pole for magnetizing the recording medium in the record mode.
