With capacities reaching up to 1GB, Hi-MD allowed for longer recording times and much higher audio quality compared to the previous format. Although it was primarily designed for audiophiles and sound recording enthusiasts, Hi-MD quickly gained traction among professionals in the fields of journalism and broadcasting due to its robustness and reliability.
In addition to its ability to store and playback high-quality audio, Hi-MD also functioned as a versatile data storage format that could be used to store various types of files, including images, documents, and even software. The introduction of a USB interface for Hi-MD devices made it possible for users to seamlessly transfer data between Hi-MD and their computer systems.
As digital audio players and more advanced portable devices came into the market, the usage of Hi-MD gradually declined, with Sony officially discontinuing it in 2011. Despite its eventual phasing out, Hi-MD played a crucial role in the history of portable audio technology and served as a significant stepping stone towards more advanced and versatile storage and playback solutions that we have today.
