A data recording device in which the data recording can be carried out at an optional speed without any loss of data using a buffer with less amount of memory. There are provided a memory buffer for storing input data; FIFO memory for dividing the data in the memory buffer into data amount corresponding to one scanning of the rotary head and storing it; data compressing or extending circuits for compressing or extending data in the FIFO memory and transferring it to the rotary head in response to a running speed of the tape; rotary head slant control circuits for controlling a slant amount of the rotary head in such a way that it may form a slant track having the same inclination as that of the slant track formed at a standard speed in response to the running speed of the tape running speed; data read-out phase control circuits for controlling a data read-out phase in the FIFO memory in response to the tape running speed; and a rotary head displacement control circuits for controlling an amount of offset of displacement of the rotary head in response to the recording phase.
