Abstract
A memory apparatus for effecting the writing or reading of information on a recording medium by a probe has a base having the probe attached thereto, a substrate supporting the recording medium thereon and movable relative to the base, and a frame containing the base and the substrate therein, and the coefficients of linear expansion of the base and the substrate are made approximate to each other since the coefficients of linear expansion of the base and the substrate are approximate to each other, any relative positional deviation between the probe and the recording medium will not occur even if temperature changes.

A memory cartridge attachable to and detachable from a memory system, said memory cartridge comprising:
- a recording medium;
- a plurality of probes for effecting at least one of writing data and reading data relative to said recording medium;
- a plurality of cantilever beams for supporting each of said probes and moving said probes relative to said recording medium;
- a base having said cantilevers attached in parallel thereto;
- a substrate supporting said recording medium thereon and having a coefficient of linear expansion approximately equal to that of said base;
- a box type case containing said recording medium, said plurality of probes, said plurality of cantilever beams, said base and said substrate;
- and
- an electrode provided on an outside of said case for being connected to an electrode provided in said memory system to provide electrical connection with said memory system when said memory cartridge is attached to said memory system.
