Tape apparatus adapted to operate with tape extending between tape reels which may be disposed in a cartridge or cassette. The apparatus includes a separate reel drive for driving each tape reel in either direction to supply or take up tape, a vacuum chamber adapted to receive a portion of the tape extending between the reels to form and support a low inertia tape loop, a capstan for driving the tape, and a transducer for recording and reproducing the information or date on the tape. The capstan and transducer are mounted along the wall of said chamber so that the tape loop extends past and has a portion on each side of the transducer and capstan whereby the tape can be rapidly moved in either direction past the transducer by the capstan. The apparatus also includes sensing means which sense the length of the tape loop on each side of the drive capstan and independently control the reel drives to supply and take up tape as the loops are lengthened and shortened as the drive capstan moves tape past the transducer in either direction and means for sensing the ends of the tape.
