In a method of and arrangement for recording blocks of data on a magnetic tape, the data is supplied at a frequency f1 1 to a buffer core store 3, with a switch Sw open until a predetermined number of bits is stored in the store 3. The switch Sw is then closed and data is recorded on the tape by a head 4 at a frequency f1 2 greater than f1 1 . During the recording the supply of data to the buffer store 3 is continued, recording being terminated when the buffer store 3 becomes empty. The recorded block length and inter-block space thus depend on the difference in value between f1 1 and f1 2 .
