-THE ISLAND LIFE-
Copy one cassette to another with the Sony WM-W800, released in 1985. This was the only double-cassette Walkman model, designed with the ability to dub tapes.
The WM-W800 was a unique addition to the Walkman range, for it was the only model that featured twin tape decks and hence the ability to copy a cassette without the use of external equipment. While the WM-W800 was the only Sony personal stereo to take two tapes, other manufacturers (e.g. Matsushita, under their Panasonic brand name) offered similar machines during this period.
One would expect that some fairly specialised technology would be required to produce a twin-tape Walkman, so it comes as a slight disappointment that the WM-W800 was constructed fairly simply, by mounting two WM-10 type mechanisms back to back. The extra electronics required for recording meant that the sub-cassette sized folding casework was discarded, but otherwise the mechanism was remarkably unaltered. The recording deck obviously required an erase head, and this was accommodated by making the record/playback head half the normal length and mounting a small permanent magnet in the space ahead of it. This magnet only hinged down during recording mode. Other additions included a mechanical interlock to sense the erase-protection tabs of cassettes and a simple pause control for the recording deck (B). This worked electrically by switching off the motor.
The recording circuits required more power than those for playback only, and so two “AA” batteries were used instead of the usual one for the other WM-10 based models. Each battery was housed in the usual place next to the heads, with one on each side of the machine. They were accessed by unclipping the trim around the tape transport buttons.
