Convert Records to CD, Convert Cassettes to CD

A 1/8" inch, analog audio tape format that has been widely used for music distribution and home recording. Although the same size housing is used, the tape thickness and length determine the recording time. Cassettes holding from 15 minutes to 60 minutes per side have been manufactured.

A smaller version of the analog audio cassette. Introduced in 1969 by Olympus, microcassettes were widely used for recording dictation and messages in a pocket-sized device. Because the recording speed is slower and the tape is thinner than an audio cassette, a tiny microcassette can hold 30 minutes per side.

Long play (LP) record albums are 33⅓ rpm vinyl Gramophone records (phonograph records), generally either 10 or 12 inches in diameter. They were first introduced in 1948, and served as a primary release format for recorded music until the compact disc began to significantly displace them by 1988.

The 45rpm record's years of greatest success began with the onset of rock and roll. The new 7 inch format was favoured by the young and in the UK sales of 45s overtook 78s early in 1958 as rock and roll established a boom in record sales.During the next few years the UK was to become a major source of popular recorded music with the advent of the British 'beat' groups which were exemplified in the 'Beatles'. This was the 'golden era' for the 45.

A device utilizing a vibrating pen to graphically represent sound on discs of paper, without the idea of playing it back in any manner, was built by Edouard-Leon Scott of France in 1857. While the mechanism, known as a phonautograph, was intended solely to depict the visual characteristics of sound, it was recently realized that this depiction could be digitally analyzed and reconstructed as an audible recording. Just such an early phonoautogram, made in 1860 and now the earliest known audio recording, has been reproduced using computer technology.

The reel-to-reel format was used in the very earliest tape recorders, including the pioneering German Magnetophons of the 1930s. Originally, this format had no name, since all forms of magnetic tape recorders used it. The name arose only with the need to distinguish it from the several kinds of tape cartridges or cassettes which were introduced in the early 1960s. Thus, the term "reel-to-reel" is an example of a retronym.
