Abstract
In an audio sound recording/reproducing apparatus, instruction information related to a document is recorded in a recording region of a semiconductor memory together with the document. In the semiconductor memory, flags related to a document portion and an instruction portion, and the addresses of the document and the instruction portions are provided. At the time of reproduction, the instruction portion is reproduced prior to reproduction of the document portion. When the content of the semiconductor memory is stored in a built-in memory in the apparatus, the instruction portion is stored before the document portion is stored. Since the instruction portion is reproduced prior to the document portion at the time of reproduction, the user does not have to retrieve the instruction portion.
