Magnetic tape memory apparatus consisting of a writing unit and a reading unit, the writing unit comprising a magnetic tape feeding device, a first and a second writing magnetic heads which are juxtaposed along the travelling direction of the magnetic tape in such a manner that the directions of magnetization thereof intersect substantially orthogonally to each other, and a logical circuit which effects change-over such that data are fed to the first magnetic head when each bit level of a plurality of bits constituting an address at each predetermined bit is "1" and that they are fed to the sevond magnetic head when it is "0," the reading unit comprising the first and second reading magnetic heads which individually read information stored on the magnetic tape by the first and second writing magnetic heads, means to combine outputs from the first and second reading magnetic heads and to thereby reproduce the data, and means to compare an output from the first magnetic head of the reading unit and an information representative of an aimed address and to lower the travelling speed of the magnetic tape when the two outputs are coincident.
