The audio protection Cactus Datashield does not damage your hifi equipment according to an article on the Register.
Earlier we reported about an article in the NewScientist that reported that Cactus Datashield could damage loudspeakers.
The technology, called Cactus, adds bursts of noise to the music data encoded on the CD. Developer Midbar Tech says the noise is eliminated by a conventional CD player's error correction system, but defeats attempts to read the music as data, as a PC-based CD drive would if it were copying the disc's contents. |
Essentially, if you try to copy a Cactus-protected CD, you end up with a CD-R full not of music, but of noise.
New Scientist technology writer Barry Fox reckoned said noise could send lethal spikes through your speakers - in extreme cases, causing them to blow.
Bollocks, says Midbar, which adds that any such effect would be "totally unacceptable". It has forced the magazine to state that "there is nothing in its technology on the market, past, current or future, that could, or would, be potentially damaging to equipment".
