Abstract

Abstract A reproduction control arrangement for a cassette tape deck, in which recording and reproduction are performed by a cassette half having a magnetic tape being mounted on the deck. The control arrangement includes a recording area having control information for record/reproduction of the magnetic tape and being provided on the surface of the cassette half parallel to the direction in which the cassette half is attached to or discharged from the deck; detecting means for detecting the recording area during the cassette tape being mounted on the cassette deck; and a processing unit for controlling reproduction of the cassette tape according to the control information recorded in the recording area. A magnetic recording piece or an optical detectable sheet attached on the surface of the cassette half is used for the recording area.
