Abstract:
A tray for carrying a magnetoresistive head of magnetic disks, said magnetoresistive head of magnetic disks comprising an arm part, an MR element attached to the arm part, and a lead wire connected to the MR element, characterized in thatsaid tray is a molding of a resin composition comprising a thermoplastic resin material and carbon fibrils incorporated therein, said carbon fibrils have a fiber diameter of 100 nm or smaller and a fiber length/fiber diameter ratio of 5 or larger, and the incorporation amount of said carbon fibrils is from 0.1 to 8 parts by weight per 100 parts by weight of said thermoplastic resin material, and said tray having a substantially even surface resistivity within the range of from 104 to 1012 &OHgr;/&square; as measured by using a probe diameter of 2 mm and a probe-to-probe distance of 20 mm.
