Originally a Compact Disc was to be 115mm/60 minutes. But Philips and Sony decided one disc should be able to contain Beethoven's 9th symphony (which is 74 min.) so playing time was strectched to 74 minutes (120mm). Also the size of the hole is based on a 10 (guilder)cent coin from Holland (one of the inventors of the CD is from Holland).
