The potential of recording on a magnetic tape modules was not lost as soon as the format was used for music playback. Instead, the magazine had a dual capacity market value at the time of its widespread use.
Compact cassettes consist of two coils that hold between a magnetic tape length plastic. This mechanism is contained in a hard plastic case with holes in the top to allow reading the magnetic tape through the mechanism, host and has several openings in the external elements that help in the rotation of the coils.
At a time when it was developed as a replacement for tapes szpulową used mainly for professional audio recording, their potential as the most common format of sound propagation was seen immediately. Due to the pressure-industrial company Philips allowed other manufacturers to a free license for the format that helped to boost her popularity.
The first cassette was sold as empty, but in 1965 in Europe was launched on a recorded tape . Under the name cassettes with music, Mercury Record Company introduced the format to the U.S. market in 1966. Preliminary proposals were limited, and the quality of the sound during the more recent relative to the tape ośmiościeżkowej, business cluster was estimated at $ 150 million at the end of the sixties.
Rapid growth of the market of cartridges can be attributed to its convenience. Much more compact than tape 8-ścieżkowe and vinyl records , electronics manufacturers want to increase the format because of the ability to move.
The first player cassette for use in an automobile cabin, was introduced in 1968. The sound quality was drastically revised in 1971, the Advent Corporation, which replaced the standard tape, commercially produced by 3M company and presented the technology to reduce noise on old cassette players. .
Symbolic player Sony Walkman appeared in 1979, with great fanfare, and other portable tape players as formats, both personal and reinforced, rozrastały. Selling cartridges surpassed these RECORDS in the 80-ies., however, before you enter a disc in the early nineties, vinyl was a favorite format of Dating.

How it works radio
In most cases, the cassette players have two modes, playback and recording . Both functions are based on the magnetic sheath covering the outer end of the tape roll of plastic material contained in a standard cassette. To understand how the tape magnetofonowa, you need an understanding of the nature of this magnetic shell.
The shell itself can be made of different magnetic materials, although iron oxide is one of the most popular. Although he is constantly magnetized, transmits electromagnetic signals characteristic of its content, which can be repeatedly overwritten.
Standard cassettes contain four electromagnetic signals, which are next to each other throughout the length of the tape. Player magazine reads only two of these signals at the same time, because each pair creates a left and right stereo signal with one side of the tape. When you fall, the tape from side a to side B, the mechanism that reads the value of the tape just get access to the second pair of channels.
Both read and write is performed according to the length of the tape, put on the head of the player built in to all players cassettes. Open the tape stretched flat via a set of rollers built into the cartridge, and a pair of spindles, usually contained within the player. Held in place thanks to kabestanowi which provides uniform speed of movement of the head, typically 1.875 inches per second. Soft clamping washer is installed in the same line as the hole is working, so the tape was stretched when in contact with metal head playing.
This head contains two small electromagnets that perform work for both playback and recording on two tracks of the tape simultaneously, depending on the settings. Can read the existing signals from the right and left side for playback or transfer new signals to the magnetic coating. While recording a lot of the players blade also uses a secondary solenoid head to remove the existing signals on the tape right before their re-entry through the bulk head.

While the format is definitely not coming back to life in recent years, a new lead cartridge magnetofonową. As soon as the music industry becomes increasingly digital, and buries the CD on a good, old formats have experienced a Renaissance.
