Hi-MD | The "Hi-MD" format can transform a standard "MiniDisc" into a versatile storage medium offering both high sound quality and high storage capacity.

What's "Hi-MD"?

"Hi-MD" is a next-generation format that has enabled the "MiniDisc" to evolve into a versatile storage medium for storing data of all kinds. While still using standard "MiniDiscs" for recording music, you can now almost double their capacity by applying the "Hi-MD" format. "Hi-MD" ensures superior audio quality by offering a choice of two different recording methods for music: linear PCM, which preserves every detail of the original sound source without compression; and "ATRAC", which can deliver high audio quality plus high compression.

Sony has also introduced the 1GB "Hi-MD" disc exclusively for "Hi-MD" use, which has the capacity to store as much as 34 hours* of recorded music. And, as a storage medium for PC data, it can also be used to hold images and text files.

*Approximate recording time when recording to a 1GB "Hi-MD" disc in Hi-LP ("ATRAC3plus" 64kbps) mode. Note that "Hi-MD" devices designed exclusively for playback have no recording function.

The "Hi-MD" format

New "Hi-MD" high density recording technology doubles the recording capacity of standard "MiniDiscs". So, in addition to using the new 1GB "Hi-MD" discs, you can apply the "Hi-MD" format to your "MiniDiscs" and enjoy much longer recording/playback times.

The "Hi-MD" format
Playback compatibility with "MD" format

With LinearPCM mode, record and playback in high quality sound without compressing the sound source.

LinearPCM mode achieves high quality sound recording without audio data compression. This function is useful for backing up your treasured music CDs. You may use optical cables to connect a "Hi-MD AUDIO " device and a CD player to retain sound quality*.

*Only CD players with optical capability can be used.

Recording with a microphone

LinearPCM mode is compatible with digital, analog, and microphone recording; you can record and play back in high quality sound, without compressing the original sound source. This function can be used in various ways such as recording a music performance.

"ATRAC3plus" - the key to recording with higher compression while preserving high sound quality

"ATRAC3plus" is the next generation audio compression technology based on "ATRAC".
While "ATRAC3" was able to compress a CD to approximately 1/10 of the original size, "ATRAC3plus" is able to compress with higher quality at approximately 1/20 of the size.


34 hours* can be recorded on a 1GB "Hi-MD"

With a high capacity 1GB "Hi-MD" disc it is possible to record up to 34 hours of music data* when recording on a stand-alone "Hi-MD AUDIO" device. 1GB capacity even allows for easy storage of large capacity music data recorded in high sound quality LinearPCM and Hi-SP modes.

*Approximate recording time when recording to a 1GB "Hi-MD" disc in Hi-LP ("ATRAC3plus" 64kbps) mode.
45 hours can be recorded on a 1GB "Hi-MD" disc when transferring "ATRAC3plus" 48kbps audio data from a computer to a "Hi-MD AUDIO" device.

Also suitable for storing computer data

"Hi-MD" is a removable, rewritable media with high capacity that is highly portable."Hi-MD" uses the FAT file system, making it possible to use "Hi-MD" formatted "MDs" and 1GB "Hi-MD" discs as versatile media for recording PC data files, such as images and text. Furthermore, as portable, rewritable PC media, "Hi-MD" complies with USB format's Mass Storage Class, ensuring that simply by connecting a "Hi-MD" product to a PC it is immediately recognized as an external storage device.

What is ATRAC?

Today, we take for granted that we can carry a whole music library with us and listen to it wherever we like.  It was Sony that first made this possible with its audio compression technology ATRAC (Adaptive TRansform Acoustic Coding)*1, which was introduced with the MiniDisc in 1992.

ATRAC: A technology that has revolutionized the way we listen to music

ATRAC uses a variety of advanced technologies to analyze digital sound data, allowing it to reduce the size of that data while maintaining superb sound quality (ATRAC*1 compresses music data to approximately 1/5 the data rate of a CD; ATRAC3 and ATRAC3plus are able to compress music data to approximately 1/10 and 1/20 the data rate of a CD, respectively).  This ability to reduce the size of data has enabled recording media to be made smaller and more tracks to be recorded on them, changing the way we listen to music.

Commencement of music distribution services

Reducing data size using audio compression technologies has made it possible to send music via the Internet.

In 1999, Sony started the Internet music distribution service "bitmusic" using ATRAC.  In this way, ATRAC has contributed to another major change in our lifestyles, making it possible for us to purchase music of our favorite artists, 24 hours a day, from the comfort of our own homes.

ATRAC is a technology perfectly suited to our network era, supporting Internet music distribution, making music available for you to listen to on your PC and ensuring high-quality recording and playback on your portable music devices.

ATRAC continues to evolve

ATRAC is evolving day by day. We are working to increase the compression ratio in order to make data even smaller while achieving even higher sound quality.  ATRAC*1 has evolved into ATRAC3, ATRAC3plus and now into ATRAC Advanced Lossless, continually providing a richer musical experience.

Sony’s original ATRAC*1 has continued to change the way we listen to music, evolving into ATRAC3, ATRAC3plus and ATRAC Advanced Lossless.
ATRAC is the collective name of all these audio compression technologies.

Technology - ATRAC3plus

ATRAC3plus Technology

ATRAC3plus represents a further enhancement of ATRAC3, featuring a new algorithm for even more precise sound signal analysis. This enables the technology to compress CD data to approximately 1/20 its original size with almost no loss of sound quality.

Main Features

1. Analyzes sound characteristics in sixteen bands

ATRAC3 divides the sound signal into four bands to analyze sound characteristics. ATRAC3plus divides the signal into 16 bands, enabling an even more precise analysis.  ATRAC3plus also uses longer analysis window than ATRAC3 to convert signals into frequency data, resulting in finer frequency resolution and allowing the technology to analyze the sound signals more precisely than ATRAC3.

Analyzes sound characteristics in sixteen bands

2. Uses more rules to replace digital patterns

ATRAC3plus replaces patterns in the digital signal just like ATRAC3, but uses more rules for substitution to enable it to cover a wider variety of patterns.  This technique has increased the rate of compression.

Digital Signal Type2

Enjoy your music on an ATRAC Audio Device product!

The ATRAC Audio Device standard has been adopted not just for portable audio players, but also for car audio, cell phones and a number of other products because it optimizes the process used to record and save a large amount of music data on high capacity media such as hard disks and flash memory devices.

Devices that support the ATRAC Audio Device standard allow users to easily download songs they purchase from music download sites that support ATRAC, such as Mora and Connect, ant to rip songs to their computers from CDs and other media.  Users can enjoy that music wherever they are.
