A semiconductor recording medium recording and/or reproducing apparatus includes: a medium holder that has a medium housing unit in which a semiconductor recording medium is detachably housed; an exterior case that has a medium entrance through which the semiconductor recording medium is inserted and ejected, and in which the medium holder is housed in a state where the medium housing unit is opposed to the medium entrance; an openable and closeable cover that opens and closes the medium entrance; a heat sink that is contactable with the semiconductor recording medium housed in the medium housing unit; and a heat sink moving unit that moves the heat sink in cooperation with an opening and closing operation of the openable and closeable cover.

Semiconductor recording medium recording and/or reproducing apparatus

A reel servo device employed in a recording and/or reproducing apparatus employing a tape cassette housing a tape as a recording medium includes an unusual running detection circuit for deciding if the tape housed within the tape cassette loaded on the tape recording and/or reproducing apparatus is wound in a slack winding state on a tape reel. If the tape running state is decided to be an unusual tape running state, tape tension data from the supply side tension arm is differentiated. If the differentiation data is positive indicating an increasing tape tension, the rewind side reel motor is controlled in a direction of slackening tape tension at the rewind tape reel side. Conversely, if the differentiation data is negative indicating an decreasing tape tension, the rewind side reel motor is torqued in a direction of tensioning the tape at the rewind tape reel side.
