Retrospective of Audiotape Data

Posted on August 13, 2021 by William

We haven’t stored software and computer data on tapes for a long time.But it used to be In fact Hobby computer standards and [Noel] have Great video about the Amstrad system (Embedded below) This is very typical and how to accelerate the process from today, you have perfect audio reproduction, especially when compared to consumer-grade audio tapes.

The cassette tape encountered several problems. Magnetic tape has inherently low bandwidth, there is considerable noise in analog circuits and magnetic heads, and the transmission speed is not necessarily constant. However, you can easily synthesize relatively noise-free sounds digitally with high fidelity and rock-solid frequencies. So basically a microcontroller, such as an Arduino, can look like a very high-quality tape drive.

The idea is similar to a modem, except that instead of a computer talking to another computer over a telephone line, it records it and listens to it again later. Ordinary tape systems can only get about 2 kbps. If you generate a nearly perfect digital signal, how fast can you get it? Watch the video to find out.

We will say that he has not finished speeding up. Analog tape drives are not a new idea. We have even seen it used in large iron tape drives.
