Adding greater versatility to the Hi-MDTM format, Sony Corporation today announced the
adoption of MP3 direct playback and the new Hi-MD PHOTO standard, which extends the
potential of Hi-MD to serve in a new role as a medium for digital still cameras.
The adoption of MP3 and the introduction of Hi-MD PHOTO enhance the Hi-MD media that is
renowned for its combination of high capacity, low cost, extreme durability, and removability,
which make it ideal both for archiving and sharing. The new features enable users to access a
wider range of music than ever, and allow simultaneous enjoyment of digital images and
music. Hi-MD continues to expand the possibilities for the development of innovative products
that will cross audio and visual boundaries.
Playback of Multiple Audio Formats
The Hi-MD AUDIO standard launch in 2004 maintained music playback compatibility with
MiniDiscs recorded using conventional MD devices while adopting uncompressed LinearPCM
(Pulse Code Modulation) and ATRAC3plus - an audio compression format that delivers high
quality sound even at high compression rates. Now, users have an additional choice: MP3
joins LinearPCM and ATRAC3plus to offer a wider choice than ever.
Hi-MD PHOTO: A Transformation into a Medium for Digital Still Cameras
Sony developed the new Hi-MD PHOTO standard to enable the recording and storage of digital
still images on Hi-MD formatted MiniDiscs or on 1GB Hi-MD discs. The picture recording
system is based on the DCF/EXIF format, which is the standard for most digital still cameras.
To provide fast retrieval of saved images via an index display, the format also adopts thumbnail
cache file system. Applied to devices such as the new MZ-DH10P Walkman, Hi-MD PHOTO
delivers more than the sum of a digital music player and a digital still camera. The MZ-DH10P
Walkman takes photos, plays back music, and runs a slideshow of pictures to accompany
songs on the full color LCD, among other features. And because MiniDiscs and Hi-MD discs
cost a fraction of flash memory media, users can easily share their photos, data, and music
with friends and family.
