Abstract

A CD player having an improved level search function is disclosed. In a level search, the judgment whether or not an optical pickup can land again on the same song is done before the jump of the pickup. When it is judged that the pickup can land on the same song, the pickup jumps a predetermined number of tracks which is determined for each of selected songs depending upon the playing time of each song. When it is judged that the pickup cannot land on the same song, the pickup jumps to the beginning of the next programmed song so that unwilling playback of non-programmed songs can be avoided. In another CD player, it is successively judged whether or not the pickup can land again on the same song in level search, based on the playing time of the song, the elapsed playing time and the playing time corresponding a predetermined number of tracks to be skipped. If the pickup can land on the same song, then the predetermined number of tracks are skipped. If the pickup cannot land on the same song, then it is skipped to the beginning of the next programmed song, whereby the pickup is prevented from landing on non-programmed songs. Therefore, level search can be accurately performed.
