Linear speed is closes at the edge, but magnetic domain density is higher at the spindle, for a uniform rotation rate. I think that the electronics ended up being designed for the average rate. PS: The encoding frequency is higher at the spindle, as well. -- Terry To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-current" in the body of the message
