Abstract
A magnetic head for recording on and reproducing from a magnetic tape is disclosed in which first and second magnetic head elements aligned in proximity in the direction of the tape feed are contained in a single case, and at least a pair of shield plates are provided for the respective head elements. The first magnetic head element comprises at least one reproducing head core, and the second magnetic head element comprises at least one recording head core, which cores have respective head gaps provided in parallel with each other and contacting the same track on the magnetic tape during its movement. Each of the shield plates has at least a first plate portion perpendicular to the direction of the tape feed disposed between the head elements and a second and a third plate portion extended in parallel with the direction of the tape feed from both ends of the first plate portion when viewed from the tape surface so as to enclose the individual head element at least in three directions, whereby magnetic leakage from one head element to the other during activation thereof is reduced.
