PROBLEM TO BE SOLVED: To provide an information signal reproducing program by which a difference of transfer speeds of first and second information signals is absorbed between an information signal recording medium and a buffer memory. SOLUTION: When difference between transfer speed for first and second information signals by one pickup head for the medium and transfer speed of the first and the second information signals in the buffer memory is absorbed, a transfer rate for the first, the second information signals by the head is assumed to Rp, a transfer rate of the first information signal is assumed to Ra, a transfer rate of the second information signal is assumed to Rb, storage capacity of the buffer memory is assumed to Ym, a seek time in which the head is shifted from a first region to a second region on the medium is assumed to Tab, and a seek time in which the head is shifted from a second region to a first region on the medium is assumed to Tab, then, the first , the second information signals are reproduced so as to satisfy Ym>[(Rp-Ra)×Ra+(Rp-Rb)×Rb]×(Tab+Tba+Fab+Fba)/(Rp-Ra-Rb).
