A portable reproducing apparatus includes a storage medium, a reproduction unit, an operation unit, and a controller. The storage medium stores a digital input signal and auxiliary associated with the digital input data. The reproduction unit converts a digital signal read out from the storage medium into a hearable sound for the reproduction output. The operation unit is provided on a main body of the portable reproduction apparatus. The controller selects auxiliary data according to an input from the operation unit and reads out a the input data associated with the selected auxiliary data from the storage medium and transmits it to the reproduction unit. The controller selects forward auxiliary data when an operation of the operation unit corresponds to a rotation in one direction around an imaginary axis perpendicular to the portable reproduction apparatus and selects backward auxiliary data when the operation of the operation unit corresponds to a rotation in another direction around the imaginary axis.
