Magnetic sound recording

چکیده
The first complete magnetic recorder (wire on a drum) was constructed in 1898 by Poulsen (Denmark). In 1938 the first recorders using plastic tape with an iron oxide layer were used. Since then, magnetic sound recording has become the most popular way of storing broadcast programmes for transmission at any time. Early attempts with temporary disc recording and photographic recording proved unsuitable for broadcast applications.

2.1 Use of magnetic tape Magnetic recording was first introduced in 1898, with the invention of the magnetic recording device by Valdemar Poulsen, a Danish scientist working on audio recording. Later, magnetic recording technology expanded from sound recording to the fields of image and information recording, with the rapid advancement of television, computers, and similar technology.

Single unit recording has been used as a well-known technique to study the electrical behavior of neurons. In this respect, the classical methods are rather expensive. In this study a simple and inexpensive method for single unit recording studies has been introduced. Computer sound card was used for data acquisition. Neural responses were saved via simple sound applicable packages and then ana...

Sound recording has taken many forms as technological developments created new and improved ways of storing information. The earliest attempts to capture and reproduce sound used mechanical methods, as Edison’s machines that connected a large horn to a tiny stylus that traced grooves in a rotating cylinder. Optical systems have long been used for film sound, but analog optical systems are compl...

Metrology, the science of measurement, is a most important activity in the recording of sound: what we record is in fact a measurement of the sound pressure or electronic signal amplitude we wish to preserve. In order to manipulate and record audio signals, we measure characteristics of the signal, generally amplitude as a function of time, and in some manner preserve that measurement. Analog m...
