We also offer audio cassette duplication. Consult our online price calculator.Normal-bias tapes are the most common and least expensive tapes. They are made with ferric oxide and therefore have a rusty brown color. This class of tape comes in voice and music quality. Our regular tape is music grade. Tapes longer than 105 minutes have a very thin base and are easily damaged, so they are intended only for special purposes and well-maintained machines. When calculating your tape length, add 7 to 10 seconds at each end, plus up to 2% in case your machines are off speed. If your program is exactly 30 minutes per side, you could ask us for tapes of 31:00 per side (or C-62s).  |
