Despite owning a record company that鈥檚 prominent in the fight against music piracy, Sony is set to launch a minidisc recorder that lets you copy four CDs in just 10 minutes. Minidiscs record music using a compression system called Adaptive Transform Acoustic Coding (Atrac). Sony鈥檚 new 鈥淣et MD鈥� recorders connect to the USB port of a PC. Software then converts audio from a CD or an MP3 website into Atrac and records it onto the minidisc at 32 times the CD鈥檚 normal playing speed.
