The storage and reproducing apparatus includes a signal processing block, a memory, a reproduction block, an operation block, and a control block. The signal processing block converts a sound signal entered, into a digital signal. The memory stores a digital signal outputted form the signal processing block and a management data of the digital data. The reproduction block at least converts a digital signal read out from the memory, into a hearable sound for reproduction output. The operation block is provided on an apparatus main body and includes a rotary operation block provided on the apparatus main body in such a manner that the rotary operation block can be rotated around a rotation center and shifted along plane which almost orthogonally intersects the rotation center. The control block, according to an input from the operation block, writes a digital signal and a management data into the memory and reads out a digital signal and a management data stored in the memory. The control block, according to a rotation direction of the rotary operation block, reads out a management data from the memory. When the rotary operation block is shifted along the plane, the control block reads out a digital signal from the memory according to a management information which is being read out from the memory.
