PROBLEM TO BE SOLVED: To provide an information signal reproducing method reproducing information by absorbing difference of transfer rates of (n) information signals between information signal recording media of a plurality of layers and buffer memories.;SOLUTION: When a head 14 reproduces a plurality of signals from one signal layer on a medium 13, the following formula is satisfied, YnRpRnSn/(Rp-Rn), when the head 14 reproduces a plurality of signals from a plurality of signal layers on the medium 13, the following formula is satisfied, YnRpRn(Sn+Fm)/(Rp-Rn), (n) information signals are transferred to the head 4 with time division between the medium 13 and a memory 19.;COPYRIGHT: (C)2004,JPO&NCIPI
