A new D-2 composite digital VTR for the present NTSC system has been developed. The D-2 system uses three different sizes of cassettes for the tape-loading mechanism, and thin metal tape of high coercivity and 13-μm thickness. To attain reliable and easy operation, an 8-head scanner and a cassette-loading mechanism were developed. All four recording and reproducing heads were designed independently and made from ferrite. All three sizes of cassettes are acceptable without an adapter and are guided by a simple mechanism, thereby achieving reliability and full function.
