Abstract
A 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, into a digital signal. The memory stores a digital signal outputted from the signal processing block and management data of the digital signal. The reproduction block at least converts a digital signal read out from the memory into an audible sound output. The operation block 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 a plane which almost orthogonally intersects the rotation center. The control block, according to an input from the operation block, writes the digital signal and the management data into the memory and reads out the digital signal and the management data stored in the memory. The control block, according to the rotation direction of the rotary operation block, reads out the management data from the memory. When the rotary operation block is shifted along the plane, the control block reads out the digital signal from the memory according to t…
