This experience makes the W-1200 a quality player with stable speed and smooth, analogue sound. Teac are highly respected in the recording field and, along with their pro division Tascam, have huge expertise in the area. This gives the option of parallel recording – ideal for when you might want two copies of a home recording. This flexible deck not only lets you record from cassette to cassette but also record on both decks. You could, for example, put the recordings on a USB stick or SD card and playback in your car, home cinema system or portable. Simply connect to a home computer or digital recorder via USB and you can archive your cassettes in CD-quality! Having the cassettes recorded in the digital domain makes for much easier access. With the Teac W-1200 you don’t just get to hear your old cassettes again – or even newly purchased ones – but also record and archive them, too.Ī great feature with the deck is the USB digital output. Rediscover precious music on your cassette tapes with this impressive Teac twin cassette deck. cogging) and are not so easy to drive as DC brushed motors.Play, record and archive your cassette tapes, with the flexible Teac W1200. consume more battery power), have unsteady speed (e.g. ![]() Stepper motors were never used in conventional cassette recorders. (See another question I answered DC Motor speed control.) The motors used for driving the tape were usually brushed DC motors with either a centrifugal governor (a small weight on a spring that open contacts at a defined speed to slow the motor) or by using the back-emf of the motor to sense and control the speed. Some also use noise reduction techniques such as Dolby Noise Reduction. There are standards set by the RIAA so that tapes are interchangeable between different machines. A cheaper alternative where low quality can be tolerated is to use DC bias, that will give a lower signal to noise ratio on playback with more hiss.Ģ) Another technique is to use equalization where high frequencies are boosted in recording and attenuated on playback to improve the overall signal to noise ratio (i.e. There are a couple of techniques used to improve the quality of the signal played back:ġ) A high-frequency AC bias is added to the signal being recorded to avoid the non-linearity inherent in the flux recorded vs the current in the recording head, without this there would be a non-linear response around zero. The standard for cassettes is where the magnitude of the magnetic flux on the tape represents the instantaneous value of the signal being recorded. The variations in quality for voice are usually acceptable. Some tape recorders such as ones for voice recording often do drive the tape by rotating the take-up reel at a constant speed - in that case the recording density will change depending upon how much tape is on the reel. ![]() The take-up reel is usually driven through a friction wheel so that it keeps reasonably constant tension on the tape but the hub speed can vary as needed. The capstan rotates at constant speed and so drives the tape at constant speed. The hubs do not rotate at constant speed in normal tape recorders - there is what is called a capstan that is kept in contact with the tape by a rubber pressure wheel.
