Abstract
An apparatus is provided for selectively recording a digital information signal on a first magnetic tape cassette having a tape with a first characteristic or a second magnetic tape cassette having a tape with a second characteristic. The digital information signal selectively has a recording mode of a first standard or a recording mode of a second standard. The apparatus comprises a first sensor for detecting the kind of the magnetic tape cassette, a second sensor for detecting the kind of the recording mode, and a controller for controlling value of recording current for the digital information signal in response to the outputs of the first sensor and the second sensor.
Claims8
An apparatus for selectively recording a digital information signal representing picture and sound information on a first magnetic tape cassette having a tape with an optimum recording current that decreases with increasing recording frequency or a second magnetic tape cassette having a tape with an optimum recording current that increases with increasing recording frequency, said digital information signal selectively having a recording mode of a first standard or a recording mode of a second standard, said apparatus comprising:
- first sensor means for detecting the kind of said magnetic tape cassette and producing an output in accordance therewith;
- second sensor means for detecting the kind of said recording mode and producing an output in accordance therewith;
- and
- control means responsive to the outputs of said first sensor means and said second sensor means for controlling a value of recording current for said digital information signal to optimize the recording current of said picture and sound information.
