The invention discloses a terminal, a screen recording method of the operation process thereof, an external device and a storage device. The method comprises the steps of opening a cache region, wherein a video of the preset time period is allowed to be cached in the cache region; in the terminal operation process, uninterrupted screen recording is executed on the terminal, on the basis of the first-in first-out and last-in last-out stacking mechanism, caching the recorded video to the cache region; when it is monitored that a preset trigger event happens in the terminal operation process, recording the happening moment of the trigger event; continuing to perform uninterrupted screen recording on the terminal, obtaining the video from the first preset period of time before the happening moment to the second preset period of time after the happening moment, and saving the video to a storage region outside the cache region, wherein the sum of the first preset period of time and the second preset period of time is smaller than or equal to the preset period of time. Accordingly, the event recording integrity can be shown, event reproduction is facilitated, and the requirement for hardware storage is lowered.
