These days we use compact discs (CDs) to play music; there aren’t very many long-playing, or phonograph, records (LPs) left. Yet not very long ago, most music was recorded on LPs and not on CDs. CDs and LPs use different technologies to encode sound and transmit it back for our ears. LPs record sound in a way similar to the way tapes record music, but CDs use quite a different technology. In the early days of CDs, there was great debate over which technology was better. CDs are now the preferred recording device.
The two big advantages to CDs over LPs are:
- They aren’t damaged as easily.
- They are smaller.
