In 2005, Sony expanded its software capabilities. A structure that can handle large-scale libraries has been introduced through data management functions.
MZ-EH50
The MZ-EH50 focuses on basic playback instead of recording or advanced control. Its plastic construction reduces weight but reflects its position below higher-end models. Hi-MD compatibility allows playback of both standard MiniDiscs and higher-capacity discs, including compressed ATRAC formats and uncompressed PCM audio. Charging is handled through a dock, and a backlit jog-dial remote provides navigation and playback control.
MZ-EH70
The MZ-EH70 emphasizes playback processing and control instead of recording capability. Its metal construction improves rigidity and durability. A digital amplifier works alongside sound processing features such as virtual surround effects and a multi-band equalizer. Playback speed can be adjusted to slow down or accelerate audio. Bundled accessories, including a charging stand and remote, create a more complete playback setup.
MZ-EH930
The MZ-EH930 is built for extended listening through a dual power system that combines an internal rechargeable battery with optional AA sidecar support. This allows runtime to be extended when needed. Hi-MD compatibility supports both standard MiniDiscs and higher-capacity discs across compressed and uncompressed formats. The device remains playback-only. Charging is handled through a dock, and bundled accessories complete the portable setup.
MZ-DH10P
The MZ-DH10P combines portable audio recording with digital photography. A built-in 1.3 megapixel camera captures still images directly onto Hi-MD discs, turning the device into both a recorder and a removable storage system. Hi-MD expands storage capacity and supports recording modes such as Linear PCM alongside compressed formats. Audio input is limited to USB transfer, removing microphone, line, and optical inputs. Recording depends entirely on software and file transfer instead of direct input.
MZ-DN430
The MZ-DN430 is built around USB transfer, removing most of the traditional recording paths found in earlier MiniDisc units. Optical and line inputs are absent, leaving computer transfer as the primary way to write audio to disc. NetMD enables high-speed transfer of compressed audio from a PC. A basic microphone input remains but with limited control. Power comes from a single AA battery, and the lack of a remote connector further simplifies the design.
MZ-RH10
The MZ-RH10 balances full recording capability with a smaller physical design. Despite its compact size, it retains microphone, line, and optical inputs. Hi-MD increases storage capacity and supports multiple recording modes, including Linear PCM. Optical input enables direct digital recording. USB connectivity allows high-speed transfer between the device and a computer.
MZ-RH710
The MZ-RH710 keeps a traditional recording layout while adding newer digital features. Microphone, line, and optical inputs support a wide range of recording scenarios. Hi-MD expands storage capacity and supports higher-quality recording modes, including Linear PCM. A digital amplifier processes playback audio after decoding. A backlit remote provides control without relying on the main unit interface.
MZ-RH910
The MZ-RH910 combines high-end materials with full recording flexibility. Its metal chassis improves rigidity and helps manage heat during extended operation. Microphone, line, and optical inputs support a full range of recording sources. Hi-MD includes Linear PCM recording. Advanced editing functions allow track manipulation directly on the device.
In 2005, the integrated structure of physical media and digital environments was strengthened. At the same time, the structural burden on operations increased.
