Aiwa AMD-100 (ca. 1993)

Not much information survives on the Aiwa AMD-100. It was a portable MiniDisc player/recorder introduced in early 1993, when the format was still new. A product announcement in HiFI-Stereo (April 1993, p.16) says the AMD-100 had "butter memory" - a buffer meant to prevent playback gaps when the unit was jolted. It also had 21-track programming and an editing mode that let the user divide, combine, erase, and reorder tracks. The announced price was $800.

Beyond that listing, almost nothing is documented about this model. The period sources located give no specifications for battery life, output power, or recording time, and no later reviews or service manuals are known to exist. It remains a scarce entry in Aiwa's early MiniDisc lineup.
