In 1986, a structure was introduced that improved resistance to vibration and shock. The smaller size of the casing allows for a design that ensures stability when carried.
D-100
The D-100 is a model that expands upon the functionality of early portable CD players while miniaturizing their configuration. It features playback control functions such as program playback, repeat playback, and A-B repeat, and the transport mechanism has also been miniaturized. The power supply relies on an external battery and it does not have a vibration-resistant mechanism. Although improvements have been made to accommodate portable use, it is intended for use in a stable installation environment. It is an advanced model of the early generation that aims to balance miniaturization with added functionality.
By 1986, the difference between sound quality and portability had narrowed. However, the device's structure was still in a developmental stage.
