Head drum device and magnetic recorder/reproducer |
摘要 |
A head drum device of the present invention prevents a magnetic tape (2) from clinging to the head drum device (3) due to electrostatic charge by using a carbon-containing synthetic resin as the material of an upper drum (33) in order to reduce the manufacturing cost for the upper drum. Also, setting the outside diameter of the upper drum (33) smaller than that of an intermediate drum (32) eliminates the need for a high-level of manufacturing precision in the manufacture of the upper drum (33). Thus, it is possible to reduce the manufacturing cost for the upper drum (33).
