In 2001, Sony added digital connectivity to MiniDisc. A structure that supports computer integration via USB connection and software has been introduced.
MZ-N1
The MZ-N1 is the first portable recorder to feature NetMD and extend MiniDisc recording to PC connectivity. It allows direct transfer of compressed audio from a PC via USB connection, reducing the need for real-time recording in many situations. MDLP allows for extended recording time, and ATRAC Type-R supports sound quality in standard recording mode. Microphone input, line input, and optical digital input are also maintained, allowing for the combined use of conventional recording methods and PC-based transfer. Connection is made via a dedicated docking cradle that serves both as USB access and charging.
MZ-B100
The MZ-B100 is a MiniDisc recorder primarily designed for voice recording rather than music playback, prioritizing ease of use and visibility. Equipped with a built-in stereo microphone and speaker, it allows for recording and playback without additional equipment, and is designed for use in meetings, interviews, classrooms, and similar settings. Recording functions, such as voice-activated recording and automatic track marking, are optimized for speech use, and content can be reviewed by adjusting the playback speed. It also supports long-duration recording via MDLP. While it includes line input and optical digital input, the overall design is that of a large, standalone unit with a direct control system.
MZ-R500
The MZ-R500 is an entry-level MiniDisc recorder with streamlined features, specializing in basic recording. It features line input and optical digital input, supporting recording from external audio sources, but all recording is done in real time, and it lacks PC connectivity. MDLP allows for long recording times on a single disc, and recording levels can be adjusted both digitally and manually. However, microphone input and remote control are omitted, with all operations concentrated on the main unit. Power is supplied by a single AA battery, emphasizing simplicity.
MZ-E501
The MZ-E501 was a mid-range MiniDisc player that supported playback of long-recording discs thanks to its MDLP compatibility. Its group mode allowed for organizing songs into folders, making it easy to handle even longer discs. Sound quality could be adjusted with manual bass and treble controls, and the remote control handled playback and display. Charging was done via a stand, ensuring compatibility and ease of use while maintaining a simple overall user interface.
MZ-E600
The MZ-E600 was a MiniDisc player that supported MDLP and offered enhanced stability and operability. G-PROTECTION pre-read audio to reduce skipping during movement. The remote control was central to operation, handling track skipping and playback control. Charging continued to use a cradle system. Furthermore, it featured a function to detect and notify the user of nearby CDMA mobile phone signals.
MZ-E606W
The MZ-E606W was a MiniDisc player that changed the way it was used by incorporating wireless operation. It adopted a control system that replaced the wired remote control, enabling playback control separate from the main unit. It continued to feature MDLP playback and G-PROTECTION, achieving both support for long-recording discs and stable playback. It also had sound quality adjustment and playback speed control, and supported charging via a cradle. Including the alarm function, it was a model with a somewhat experimental character.
MZ-R700
The MZ-R700 is a mid-range MiniDisc recorder that offers a full range of recording inputs while maintaining ease of use and reliability. It features microphone input, line input, and optical digital input, supporting both voice and music recording. MDLP enables long recording times, and G-PROTECTION reduces skipping during playback. Recording levels can be adjusted both digitally and manually. A remote control for playback is included, but it lacks a display; operation is primarily handled by the main unit.
MZ-E707
The MZ-E707 was a high-end MiniDisc player that expanded the range of adjustments during playback while maintaining supported formats. It supported playback of MDLP recording discs and ensured stability during transport with G-PROTECTION. It featured playback speed adjustment and manual sound quality control, allowing for fine-tuning during listening. Operation was done via remote control, and charging was done using the cradle. It was a model that expanded the range of adjustments that users could directly make, rather than relying solely on presets.
MZ-G750
The MZ-G750 is a MiniDisc recorder based on the R700 series' recording functions, with radio functionality integrated into the remote control. It features microphone input, line input, and optical digital input, supporting both analog and digital audio sources. MDLP enables long recording times, and G-PROTECTION reduces skipping during playback. Recording levels can be set automatically or manually. The AM/FM tuner is built into the remote control, allowing for independent radio reception, but it does not support recording of broadcast content.
MZ-E909
The MZ-E909 was a top-of-the-line MiniDisc player that combined high-quality materials with excellent long-playback performance. It featured a magnesium chassis, achieving both lightweight design and rigidity. MDLP support allowed for playback of long-recording discs, and G-PROTECTION ensured stable playback. ATRAC processing improved audio reproduction, and the remote control supported detailed track information, including Japanese language display. Battery performance was also designed with long playback in mind.
MZ-R909
The MZ-R909 is a high-end MiniDisc recorder in the R series, featuring refined controls and display performance. Equipped with microphone input, line input, and optical digital input, it supports a wide range of applications, from voice recording to music recording. MDLP allows for extended recording time, and recording levels can be adjusted both digitally and manually. It also includes a group function for organizing long recordings. The combination of a rotary jog dial and multi-line display ensures operability befitting a high-end model, including dual level meters and display settings.
In 2001, an integrated structure of disk architecture and digital environment was introduced. This structure was subsequently applied to subsequent models.
