Default Re: Question on Recording speeds

As more and more audio manufacturers turned to producing record players, the idea of a 78 RPM turntable became the norm. This is because the 3600 RPM motor used within the turntable saw peak performance at 78.26 RPM.

Format wars is nothing new in the audio and video department. From VHS vs. Beta to Blu-ray vs HD-DVD, companies have often put out competing formats. RCA, which failed miserably in the 1930s to release a 33 to the public went out to release a 45 RPM.

The record was smaller than the other options. Ultimately, RCA released the format in order to directly compete with the Columbia Record 33. The 45 of the time did not provide much in terms of an advantage over 78s, and Columbiaís system could play both 33 and 78, so few manufacturers picked up on the 45s.

While the 45 didnít provide any real benefit over the 78, it was a smaller size. So, by the early 1950s, nearly all record manufactures focused on systems that could play both the 33 and the 45. The 78 more or less dropped out shortly after the conclusion of World War II.

The faster a record spins, the better it sounds. With that in mind, there is only so much a record can play. This ultimately proved to be why the 45 outlived the 78. Of course, everyone has their own listening preferences, so there are still fans of the 78s.

All three speeds though have played an interesting role in the development of enjoying audio at home. There are certain limitations to certain speed records in how they are produced impacting their playback.
