About Hi-MD
“Hi-MD” is a new MiniDisc format.
Incorporating the new ATRAC3plus audio compression technology, Hi-MD is a new recording format
that delivers longer recording times than ordinary MDs. Hi-MD discs can also be used as a computer
storage medium for non-audio data such as text and images. This recorder supports Hi-MD only.
For more details on Hi-MD, refer to the supplied flyer “What you can do with the Hi-MD Walkman”.
