Abstract:
A data storage medium support member is produced by resin molding. The data storage medium support member includes an accommodating portion, a guide portion, and a gate cut portion. The accommodating portion accommodates a magnetic member around a central axis. The guide portion has a guide surface for guiding an inner edge of a disc, and is arranged radially outward of the accommodating portion. The gate cut portion is formed on a rear surface of the guide portion. The data storage medium support member can be produced by the resin molding while securing space for accommodating the magnetic member and preventing an increase in the axial dimension of the data storage medium support member.
