In 2004, MiniDisc was maintained as a parallel structure to file-based audio sources. A configuration was adopted that addresses the need for enhanced recording and management functions.
MZ-EH1
The MZ-EH1 was an early playback-only player compatible with the Hi-MD format. It supported both standard MiniDiscs and high-capacity Hi-MD discs, and also supported uncompressed audio playback, expanding the range of content it could handle compared to previous models. The unit itself was playback-only; an external recorder was required to create Hi-MD content. The remote control featured a multi-line display, allowing for detailed song information, including Japanese language support. It employed a lithium polymer battery, ensuring sufficient capacity while maintaining a compact size.
MZ-NH1
The MZ-NH1 was introduced as the flagship recorder during the early stages of Hi-MD's development, featuring full recording capabilities and a highly rigid aluminum casing. Equipped with microphone input, line input, and optical input, it supports both analog and direct digital recording without the need for a PC. Hi-MD expanded recording capacity, and multiple recording modes, including Linear PCM, were available. USB transfer support also provided greater flexibility in file management compared to previous models. With a configuration that allows for recording, editing, and transfer all in one unit, the dense feel of the metal body contributes to its flagship-like finish.
MZ-NH3D
The MZ-NH3D is a simplified Hi-MD recorder that retains essential recording functions while omitting many external inputs. A microphone input is included for direct recording without a PC, but line and optical inputs have been completely removed. Hi-MD compatibility expands recording capacity and supports both compressed and uncompressed recording modes. However, its practical use is quite limited, with the main audio capture being via USB. The microphone input is intended for simple recording on the go. With its built-in rechargeable battery and compact design, portability is a top priority.
MZ-E520
The MZ-E520 was a compact MDLP player that prioritized playback performance over feature expansion. It supports both standard MiniDisc and MDLP recording. Audio processing is handled by a digital amplifier after decoding, and the playback quality of MDLP recordings is enhanced by ATRAC Type-S. Sound quality can be adjusted with a multiband equalizer, and charging is done via a dedicated stand. The backlit remote control is the main control interface.
MZ-N520
The MZ-N520 is an entry-level NetMD recorder that simplifies its design while retaining the necessary connectivity for MiniDisc recording. It features line input and optical input, supporting recording from external devices. Furthermore, it includes USB transfer, allowing it to handle PC-based audio. MDLP extends recording time through compression, and ATRAC Type-S improves the playback quality of that compressed recording. It also supports direct recording via optical input, retaining ample MiniDisc recording capabilities despite being an entry-level model. Powered by a single AA battery, its ease of use is straightforward.
MZ-NH600
The MZ-NH600 is a Hi-MD recorder whose specifications vary significantly by region, making it a model whose characteristics as a recording device differ depending on the market. With line input and optical input, it can be used like a conventional recorder with added PC connectivity. Hi-MD expands recording capacity and supports higher-quality recording modes. USB transfer support allows for operation that doesn't rely solely on real-time recording. While it's easy to use with its AA battery operation, the regional differences themselves are what largely determine the evaluation of this model.
MZ-E630
The MZ-E630 was a later-generation MDLP player that focused on refined playback quality. It supported both standard and long-playback MiniDisc formats, and ATRAC Type-S enabled more natural playback of compressed recordings. The sound during playback was shaped by a digital amplifier and internal signal processing, and it also featured functions such as bass boost and volume limiting. The main control was the remote control, which also handled track skipping and group functions.
MZ-NH700
The MZ-NH700 is a mid-range Hi-MD recorder that, while lacking the premium materials and build quality of higher-end models, offers a full range of inputs necessary for recording. It features microphone, line, and optical inputs, supporting both analog and digital recording without limitations. Hi-MD expands recording capacity and supports both compressed and uncompressed recording. USB transfer is also included, allowing for relatively smooth connection with a PC. With its practical AA battery operation, it's a well-rounded device that prioritizes usability over flashiness.
MZ-E730
The MZ-E730 was a high-end MDLP player that balanced playback adjustment capabilities with superior sound quality. Its aluminum chassis ensured both compactness and high rigidity. It lacked recording capabilities, focusing solely on the playback experience. The enhanced digital amplifier combined with sound processing functions including virtual surround and equalization, and playback speed could be adjusted without external devices. Charging was via a dock, eliminating the need to plug in cables directly. Operation was primarily controlled by the remote control.
MZ-NH900
The MZ-NH900 is a high-end Hi-MD recorder that boasts not only full recording capabilities but also a refined build quality and construction. Its metal chassis enhances rigidity, ensuring stability even during long recording and playback sessions. It features all major recording inputs, including microphone, line, and optical inputs. Hi-MD supports uncompressed PCM recording, and USB transfer allows integration into PC-based workflows. It also includes on-board editing functions, allowing for complete track management without external software.
MZ-N920
The MZ-N920 is a fully recording-compatible model equipped with microphone, line, and optical inputs, and also supports USB transfer. It features enhanced playback quality through ATRAC Type-S and a digital amplifier, and includes an equalizer and virtual surround sound. Sound quality can be adjusted without modifying saved data. The control system is divided between the main unit and a high-performance remote control.
Qualia 017
Long Description: "The Qualia 017 is a playback-only MiniDisc player from Sony's Qualia line. Its casing is constructed from solid, machined brass, giving it significantly greater mass and rigidity than typical portable players. It lacks recording capabilities and is limited to standard MiniDisc playback only. This product is designed as a complete playback environment, including the included stand and earphones. It prioritizes texture and presence over portability and functionality."
In 2004, the gap between product structure and market structure widened. On the other hand, the structural advantage in recording capabilities was maintained.
