Abstract
To provide an image signal recording system for compressing image signals and storing compressed image data onto a storage-medium PC card; which prevents at least occurrence of an abnormal interruption of recording operation in the system. Conventionally, if a write data transfer rate of the PC card is relatively slow, full-motion picture data recording is disabled to cause an abnormal interruption of recording operation in the image signal recording system. Although there are conventional arrangements specifically designed for use with a dedicated card having a high rate of write data transfer, any arrangement applicable to write data transfer rates of various kinds of general-purpose PC cards has not been devised yet. The present invention provides an image signal recording system which is capable of detecting a write data transfer rate of each kind of PC card for inhibiting full-motion picture data recording or selecting a write data transfer rate meeting the detected transfer rate, thereby accomplishing above object.
