Car makes odd sound when starting

When I turn on my car it makes a sound like something is lightly hitting metal. Like a screwdriver tapping a pipe. It only does it once or twice after I stop turning the key. The car turns over and once its started it doesn't make this sound anymore. It only does it when I go to start it. Can anyone tell me what this sound is and how to fix it please?

 

You could have a starter gear not retracting all the way and it's tagging the flex plate teeth.

 

sounds like starter drive zinging the flexplate...

 

Is there any way to fix this?

 

Replace the starter.
