Abstract
Method in which a magnetic head unit is manufactured from a magnetic head and a support. The magnetic head is manufactured by providing a thin-film magnetic head structure with a ground conductor on an electrically conducting substrate. Before the magnetic head is secured to the support, an electrically insulating layer present on an outer side of the substrate is removed, whereafter an electrically conducting contact layer (39) is formed on the surface obtained. By securing the magnetic head to the support, the contact layer will be in contact with parts (43a, 43b) of the support for the purpose of grounding the support.
