60 minutes MD spins at 1,4 m/s linear. 74 minutes MD spins at 1,2 m/s linear. 80 minutes MD has the same linear speed than 74 minutes MD and thinner groove to increase the capacity. So, is it possible to make MD with a groove as thin as MD 80's but with a slower linear speed to increase the recording capacity (why not MD 90 or 100 minutes of stereo recording?) ----------------------------------------------------------------- To stop getting this list send a message containing just the word "unsubscribe" to [EMAIL PROTECTED]
