ABSTRACT:
A magnetic tape player which includes a tape transport speed selector capable of assuming one of first and second modes during which the magnetic recording tape is transported at a first transport speed and a second transport speed which is 1
(n being an integer other than 1) of the first transport speed, respectively, a remaining tape length measuring means for measuring a length of time available for recording information to an end of the magnetic recording tape when the magnetic recording tape is transported at the first transport speed, a recording timer for outputting a remaining time signal indicative of the balance between a preset recording time and the length of time actually passed in recording and for outputting a terminating signal necessary to terminate the transport of the magnetic recording tape when the balance becomes zero, and a comparator for comparing the available recording time signal and the remaining time signal with a conversion value during information recording with the magnetic recording tape transported at the second transport speed. If the available recording time signal is higher than the remaining time, the magnetic recording tape is transported at the first transport speed, but if the available recording time signal is lower than the remaining time, the magnetic recording tape is transported at the second transport speed.
