RECORDING/REPRODUCING APPARATUS SUCH AS A MEMORY APPARATUS |
摘要 |
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.
