Se je že kdo vprašal, zakaj zgoščenka (CD) lahko predvaja do 74 minut glasbe in ne 60 ali 64? Na spletu sem našel legendo, ki pravi, da je dolžina omenjenih minut prilagojena dolžini Beethovnove devete simfonije.
Philips in Sony sta skupaj sodelovala pri izdelavi zgoščenke (CD-ja) in originalni prototip je meril 11.5 cm ter je lahko predvajal do 60 minut glasbe. Vendar pa Sony-evemu predsedniku Norio Ohga to ni bilo všeč, saj je bil za takratne razmere format diska premajhen in je predlagal za 0,5 cm večjega, torej 12 cm in ki bi lahko predvajal do 74 minut glasbe. Čisto po naključju pa naj bi bilo predsednikovo najljubše klasično delo prav deveta simfonija. Še večje naključje je, da je omenjeno delo bilo tudi ženino najljubše.
Druga razlaga pa je, da naj bi legendaren dirigent Herbert von Karajan zahteval, da bi morala zgoščenka predvajati celoten posnetek devete simfonije. Karajan je bil velik zagovornik izdelave zgoščenke in veliko ljudi je takrat zahtevalo, da bi morala biti ravno ta simfonija referenca, kolikšna dolžina predvajanja bi morala biti na zgoščenki.

Zanimiv prispevek, tudi če to ni res, je moral imeti nekdo dobro domišljijo.

Zanimivo. Sem posrčala internet in zgleda, da informacija drži:
When the Compact Disc Digital Audio standard came out in 1980, there was a curious fact about it: It was 74 minutes long. Not 60 minutes. Or an even 70 minutes. Seventy-four. And it was all one deaf man's fault. Updated
The fault of a deaf man and one of the best musical compositions ever written—one that gives me goosebumps every time I listen to it on my big honking Denon reference headphones: The Symphony No. 9 in D minor, Op. 125, the final great work of a Herr Ludwig van Beethoven, of Bonn, Germany.
But how?
Picture this: The 1970s, the greatest rock era of them all. Plus, disco. The exact year: 1979. The year the Rolling Stones recorded Emotional Rescue, Debby Harry rocked everyone with Heart of Glass, and Chic made the world dance with Good Times. It was also the year in which Philips and Sony were working on the first audio CD standard.
Philips wanted a 11.5-centimeter disc, while Sony wanted a 10-centimeter format. Both were enough to fit any of those vinyls, the smaller size capable of storing 60 minutes of 16-bit 44,056 Hz stereo music.
But that wasn't enough. Norio Ohga said so. Ohga was a man mad about audio. He trained as an opera singer and, after listening to Sony's tape recorder for the first time, he sent a letter criticizing its audio quality. He was offered a job at the company, and his influence was so big that he became president of Sony in the 80s. But, back then, he was just overseeing the project and he demanded that the CD format should be able to play back the whole Ninth Symphony.
According to Philips, the "longest known performance lasted 74 minutes [...] a mono recording made during the Bayreuther Festspiele in 1951 and conducted by Wilhelm Furtwängler." 60 minutes wouldn't cut it, and so it became 74 minutes—12 centimeters.
At least, that's what some people say. Others say that it was famed Austrian orchestra and opera conductor Von Karajan who wanted the format to hold the entire Ninth. Von Karajan was instrumental in making the format big among the audio connoisseurs, and put that as a condition for supporting it.
However, Philips' chief engineer Kees Immink has a completely different story. He says that 12 centimeters was the final length because it was a neutral size. Neither Sony's nor Philips'. But that, my friends, I don't want to believe, even while it's the truth. I prefer to believe that it were the crazy German and the mad Japanese that made it 74 minutes. It's just so much more romantic.
