A portable media player communicates with a host computer for enabling a user of the player to manage media distribution using the control software of the host computer. The host computer can send a GUI that is displayed on the otherwise 'dumb' player, and the user can view the GUI and press a single button to command the control software to download a media title to the player. The host computer can periodically poll the player to determine its status.

An optical recording and reproducing apparatus comprising an erroneous recording prevention component which prevents this apparatus from making an erroneous recording or erasing operation while it records data on a writable disk. The apparatus is arranged such that, while it is performing a recording or erasing operation, a state of its beam of light just about to go off the control point of tracking and a state of its beam of light just about to go off the control point of focusing are each monitored and, when either of the states is detected, the recording or erasing operation is canceled. Hence, laser power of the beam of light can be controlled before the beam of light completely goes off the control point of tracking, thereby preventing the beam of light from affecting data having been recorded along other tracks.
