This "Densuke" series portable cassette recorder was designed to strict standards for audio quality—evident in features such as its capstan servo, "disc drive" mechanism, and Dolby NR. The designers sought high performance in a small, light unit. With less surface area available, some controls were grouped on the front and other, less-used controls were moved inside the cassette cover. It is a well-organized layout that shows great attention to detail. A die-cast case makes the recorder exceptionally durable.
