In a cassette tape recorder for recording signals on a magnetic tape wound on a pair of reels of a tape cassette or reproducing signals from the tape, a control circuit for controlling a tape transport mechanism detects the amount of the tape remaining unwound and extending to the tape tail end, and controls the tape speed based on the tape position corresponding to the detected amount of the remaining tape. The control circuit estimates the thickness of the tape and alters the tape position where deceleration of the tape is to be started, in accordance with the estimated tape thickness. Consequently, even when the tape thickness varies from tape to tape, the time required for winding up the magnetic tape can be shortened by giving specified speed variations to the tape in the high-speed winding mode.
