Abstract
PURPOSE: To achieve the construction to minimize the relative size against thermal expansion, by placing the fitting position of the rotating head to the shaft so that the position is almost the same as the head section axially.
CONSTITUTION: The model diagram showing the basic constitution is illustrated. The reference surface S indicates the position where the cylinder is installed on the reference chassis plane of the VTR and also indicates the average position of the thrust support N being the tip of the rotating shaft 9, the rotating head support P, and the part where the rotating shaft 9 is inserted to the bush 9. The thermal expansion ΔH of the distance H between the reference surface S and the head 2 is shown in equation I, where Δl1WΔl4 are thermal expansion of l1Wl4 in table 1. By locating the position of the support P lower than the position of the head 2, (l1= -6mm in table 1), the thermal expansion between the head and tape can be made within the permissible torelance of VTR.
