ABSTRACT:
Tape dropouts are reduced, in a digital magnetic tape recorder having a tape length metering roller that provides running length information, by using specially arranged tape guide rollers that cooperate with the metering roller to define a V-shaped tape path to lessen the stresses imposed upon the magnetic tape and to minimize the extent that the tape wraps around the metering roller. The metering roller is arranged at the vertex of the V-shaped tape path with a wrap angle of about ninety degrees and by specifically arranging the guide rollers and the capstan-pinch roller on the tape recorder top plate the tape path length is reduced, thereby accommodating additional apparatus on the top plate.
