12" 45 RPM records: What's the story?


What's the advantage of producing these? If there is one, why aren't they all 45RPM?

Rushton...Just to be clear...it's easy to edit out just before the music starts. It can't be removed throughout the music and is a significant problem with very old archived tapes.
Eldartford, I am gathering a number of cds and the tracks showing pre-echo.
Nsgarch, go to this link and scroll down to the section about disc cutting. It will explain adjacent groove deformation due to a number issues involved in the cutting process.
Onhwy61,
Thanks that was interesting. I assume the vinyl details are accurate, although the bit about CD or DVD compared to analog was completely incorrect. (The author is comparing raw analog signals and the raw analog output of CD or DVD very precisely resembles the original analog signal not a staircase. Comparing Digital information directly to its translated Analog counterpart is like comparing the computer binary code for a work of Shakespeare with the analog book and saying that this bunch of ones and zeros clearly has absolutely nothing to do with this work of Shakespeare.)
