Method of making a multitrack magnetic head employing double helix structure |
摘要 |
A multitrack magnetic head is made from an electrically conductive first helix formed on an iron wire that is, in turn, wound to form a second helix. By longitudinally cutting along one side of the second helix, the first helix is severed into respective coils on discrete gapped cores.
