A recording/reproducing apparatus () includes a storage section () having a content attribute database (DB) and a point database (DB). Further, a point calculating section () of the recording/reproducing apparatus () extracts attribute information sets for each content item from the content attribute database (DB). Further, deletion factor points associated with deletion factors corresponding to the extracted attribute information sets are extracted from the point database (DB) for each content item, and evaluation points are calculated in accordance with the extracted plural deletion factor points. This allows the user to appropriately reserve a space required in a recording medium.

Recording apparatus, method for controlling recording apparatus, control program of recording apparatus, and computer-readable recording medium

To enable a recording device recording a video/audio signal and information necessary for utilizing the video/audio signal to copy the video/audio signal with the converted bit rate, encoding format, etc., to another recording device when utilizing the video/audio signal by the another recording device, and to move only the information necessary for utilizing the video/audio signal between the recording device and the another recording device. A recording device comprises: an input portion that inputs a video/audio signal; a recording portion that records the video/audio signal and information necessary for utilizing the video/audio signal; and a converting portion that converts the recorded video/audio signal. The recording device, leaving the original video/audio signal, copies the video/audio signal whose bit rate, encoding format, etc., have been converted at the converting portion to another recording device and moves the information necessary for utilizing the video/audio signal to the another recording device. After the video/audio signal is utilized by the another recording device, only the information necessary for utilizing the video/audio signal is moved again from the another recording device to the recording device.
