ABSTRACT OF THE DISCLOSURE A digital signal recording apparatus in which a sampling frequency of digital information signals to be recorded cannot be completely divided by a frequency of a unit of an error correcting code consisting of a plurality of samples in the encoding process of error correcting code, comprising an analog to digital converter for converting analog input signals into digital information signals, an encoder for performing encoding of error correcting code with regard to the digital information signals, memory means for the encoding, an address generator for controlling write operation and read operation of the memory means and recording means for recording output data of the encoder onto a magnetic tape by rotary magnetic heads, the digital signal recording apparatus comprising: means for setting a numerical value of 2 or more which is an integer value near the quotient obtained when the sampling frequency is divided by the frequency of the unit of the error correcting code; means for comparing a count value of the number of input samples to be recorded and a count value selected from the numerical values of 2 or more and outputting a count comparison signal; word control means for determining the number of samples included in the unit in accordance with the count comparison output signal; and means for controlling an address in a memory in the recording apparatus by means of the word control means.
