Abstract

An information signal processing apparatus according to the present invention is arranged to receive, as an input, an information signal to temporarily store therein the input information signal and to temporarily store therein management information prepared during a recording of the information signal in the recording medium, thereby recording the temporarily stored information signal and management information in the recording medium. Accordingly, it is possible to record an information signal having a large amount of information in the recording medium without lowering a recording speed and it is also possible to easily reduce the size, weight and cost of the apparatus.

Claims

1. A camera comprising:
