Abstract

PURPOSE: To obtain a lightweight device at the low cost of production by making a cylindrical stationary drum, having a magnetic tape guide passage on its outer circumference, with thermosetting resin with constant characteristics.
CONSTITUTION: Between upper stationary drum 1 and lower stationary drum 2, rotary disk 3 with magnetic head 7 is provided and slightly concaved magnetic guide passage 8 is also provided on the surfaces of stationary drums 1 and 2. In this constitution, stationary drums 1 and 2 are formed of a hardened material of a thermosetting resin composition; and the composition includes unsaturated polyester resin, thermoplastic resin having affinity with the unsaturated polyester resin, and a powdery or granular inorganic filler and antistatic agent, and the roundness of each stationary drum made of the cmposition never increases above 10μm even after heating at 90°C for 1400hr.
