发明名称 Magnetic head
摘要 <p>In a magnetic head which can be mounted in large number on a rotating drum in large number and cope with a highfrequency band, a leading core and a trailing core can be easily discriminated from each other, and the type of a magnetic head can be easily identified. There is disclosed a magnetic head (1) including a pair of magnetic head halfmembers (4a,4b) obtained by forming magnetic metal (3a,3b) layers serving as magnetic cores on a part on a nonmagnetic substrate and a thinfilm coil (6a,6b) buried in the pair of magnetic head halfmembers, the pair of magnetic head halfmembers being joined to each other through a magnetic gap (g) formed between the magnetic metal layer of one magnetic head halfmember and the magnetic metal layer of the other magnetic head halfmember, wherein an identification groove (8) is formed in one magnetic head halfmember, and the formed identification groove makes the appearances of the pair of magnetic head halfmembers asymmetrical.</p>
