What other format was the Greatest Hits released on besides the analog sound storage medium known as LP?
LP record The LP (from "long playing" or "long play") is an analog sound storage medium, a vinyl record format characterized by a speed of 33 ⁄ rpm, a 12 or 10 inch (30 or 25 cm) diameter, and use of the "microgroove" groove specification. Introduced by Columbia in 1948, it was soon adopted as a new standard by the entire record industry. Apart from a few relatively minor refinements and the important later addition of stereophonic sound, it has remained the standard format for vinyl albums.
The Number Ones The Number Ones is a compilation album of hits by The Beatles released in 1983 by EMI on the Parlophone Records label in Australia (PLAY1024). Released on both LP and cassette, it is an alternative version of the album titled "20 Greatest Hits" in most of the world. Due to timing problems, EMI included a three-track bonus EP (A-980), with the 20-track LP. The cassette version contains all 23 tracks as cassettes do not have the length limitations which LPs have. The album spent one week at the top of the Australian album charts in 1983.
