Abstract
The support that bears and positions the head in a head holding apparatus is further supported by a heat-compensating member, so that when the support is expanded by the heat source of the head holding apparatus, the heat-compensating member expands in the direction opposite to the direction of expansion of the support. Moreover, supplying of heat to the support and heat-compensating member is further alleviated by insulating said heat source with an insulating material. The amount of displacement of the recording element per unit of time with exposure to heat is controlled by the above-mentioned structure and effects.
Claims6
A head holding apparatus holding a head or the assembly on which said head is loaded comprising:
- an anchor for anchoring a position of said head holding apparatus;
- and
- a support bearing said head at a predetermined position with said anchoring means as a reference, wherein said support is supported by a heat-compensating member arranged parallel to said support so that when said member expands with exposure to heat, the heat-compensating member expands by a same amount as said support to control the amount of displacement of the head per unit of time with exposure to heats;
- an insulator for reducing the temperature difference between said support and said heat-compensating member and located therebetween;
- and
- a connector for connecting said head holding apparatus to a testing device.
