A laminated multi-channel magnetic tape head apparatus has alternate lamina of copper and iron, with the iron lamina having gaps for recording/reproducing separate tape channels of multi-channel tapes. A copper insert and suitable connectors form electrical conducting loops around a portion of each magnetic lamina, magnetic flux being induced in the magnetic lamina during recording and current being induced in the conducting loops during reproducing. An iron core piece with a coil mounted thereon magnetically transfers an electrical signal between a current conduction loop and the coil, with the coil being connected to a sound recording/reproducing system. Either the iron core piece is shifted from one magnetic lamina to another or switching between iron core pieces occurs thereby positioning the pickup portions of the tape head to the various tracks on the tape without physically moving the entire head assembly.
