Abstract
A recording/reproducing apparatus includes a recorder which records plural types of picture signals and picture information representing types of picture signals on recording tracks of a recording medium; a setting circuit which sets a type of picture signal to be reproduced from the plural types of picture signals; a search reproducer which scans transversely across the recording tracks and reproduces the picture signal and the picture information of the type set by the setting circuit from the recording tracks; a tracking controller which controls the search reproducer so that the picture information of the type set by the setting circuit can be normally detected during search reproduction; and a memory which stores the picture signal reproduced by the search reproducer during plural scans and forms a search reproduction picture based on the picture information reproduced by the search reproducer. The recording/reproducing apparatus may include a reader which reads the search reproduction picture from the memory. The search reproduction picture may changes intermittently during search reproduction.
