Abstract

In the disclosed recording and/or reproducing apparatus, a switch detects whether the recording medium is mounted on the apparatus and a signal detecting head detects whether a signal is recorded on each of the recording tracks of the medium. In response to the switch detecting that the medium is mounted on the apparatus, a control circuit causes the signal detecting head sequentially to scan the recording tracks on the recording medium one after another. A memory stores the output of the signal detecting head during the sequential scanning operation so that a vacant track search operation can be accomplished within a short period of time.
