Abstract
Trays for carrying magnetic heads for magnetic disks are provided, such as magnetic-head carrying trays which are less apt to cause electrical damage due to electrostatic discharge, an excess flow of contact current, etc. or physicochemical damage such as particle detachment, contamination with ions, etc. The trays for carrying magnetic heads for magnetic disks are trays obtained by molding a conductive thermoplastic resin composition containing a conductive loading material, e.g., a conductive filler, and have a surface resistance of from 103 to 1012 &OHgr;.
