A recording apparatus, a recording method, a salvage apparatus, a salvage method, and a program for reading data from a recording medium that has failed to normally end a recording process. Each of salvage markers contains a recognition pattern for recognizing a salvage marker, and identification information for identifying files to which audio data 'Audio', and video data 'Video' belong. If the recording process fails to end in a normal state, the salvage markers are detected from the recognition pattern contained in the salvage markers, and the file having the audio data and the video data belonging thereto is identified by the file identification information. The present invention is applicable to a video processing apparatus.

Recording device and method, salvage device and method, and program

A magnetic recording and reproducing apparatus, e.g., a video tape recorder for recording and reproducing digital video signals etc., is intended to reliably perform a tracking control even when recording tracks are formed with high density. A first pilot signal having a large azimuth loss and a second pilot signal without azimuth loss are recorded in a recording track, and a rough tracking control operation and a fine tracking control operation are executed on the basis of the second pilot signal and the first pilot signal respectively.

Magnetic recording and/or reproducing apparatus

In a tape guide system having a tape guide device for guiding a magnetic tape in a video tape recorder or the like and which comprises a tape guide and an ultrasonic vibrator fixed to the tape guide for vibrating the tape guide with a standing wave, a drive device supplies a drive signal to the ultrasonic vibrator, and a temperature compensating circuit is provided for effecting temperature compensation of the drive signal supplied from the driver device to the ultrasonic vibrator.
