ABSTRACT:
The multi-track head includes more than one head chip attached onto one head base. The head chips are respectively attached onto the divided front end parts of the head base, and the relative positions of the front end parts of the head base are adjusted so that the positions of the gap ends in the head chips are set precisely to a predetermined value, before the head chips are fixed. For these reasons, it is not necessary to adjust the position of each head chip after the head chips are arranged in a rotary cylinder. It is therefore possible to obtain a head having a size which can be accurately adjusted, regardless of the size of the head chip, even when the head chip is extremely small. A bonding material is provided between the divided front end parts to secure the front end parts and the chips mounted thereon in place after they have been displaced to align them with recording medium track locations.
