ABSTRACT:
An analog-cum-digital video recording and reproducing device which can perform recording and reproduction of HDTV digital signals as well signals as well as recording and reproduction of VHS analog signals is disclosed. The device has separate recording and reproduction processing systems for processing HDTV digital signals and VHS analog signals, digital recording and reproduction heads, and analog recording and reproduction heads, which can perform selective recording and reproduction of HDTV digital video signals and VHS analog video signals on or from a VHS tape by controlling running of the tape and rotation of the head drum to speeds appropriate to the respective signal processing system. It further allows use of an existing VHS or S-VHS tape for recording and reproduction of analog or digital video signals by providing means for interchangeable reproduction of an existing VHS tape, which allows recording of the high quality HDTV signals on a 1/2" VHS tape. The device can control the mode to be put into a digital recording mode or an analog recording mode when performing a recording according to the selection of a user, and can make automatic changeover to a digital reproduction mode or an analog reproduction mode according to determination of the kind of signals reproduced from a recorded tape when performing a reproduction. The device can record and reproduce analog video signals and digital video signals into high-quality images by mounting heads for an analog signal band as well as heads for a digital signal band on one head drum.
