Abstract
A reproduction control method adopted by an information-processing apparatus such as a personal computer for the purpose of protecting copyrights imposes a restriction on an operation carried out by a media reproduction apparatus such as a disc drive apparatus to reproduce musical data or the like (from a recording medium mounted on the media reproduction apparatus). A command issued by the processing main member of the information-processing apparatus (including application programs and an OS) to the media reproduction apparatus such as the disc drive apparatus to read out data recorded on the recording medium in a predetermined format is monitored. If the issuance of a command to read out data recorded in a predetermined format is confirmed, a copyright protection process is carried out to protect a copyright. The copyright protection process is a process to prohibit or conditionally permit a suck-up operation (to transfer the musical data from the recording medium to the personal computer).
