uploading file
at the first if you save file into database by giving path public_path() once it not need to used in delete method again

public function store_file(Request $request)
{
   if($request->hasFile('file'))
   {
      $fileExtention = $request->file('file')->getClientOriginalExtension();
      $name = time().rand(999,9999).$request->filename.'.'.$fileExtention;
      $filePath = $request->file('file')->move(public_path().'/videos',$name);
      $video = new Video_Model;
      $video->file_path = $filePath;
      $video->filename = $request->filename;
      $video->save();
   }
   return redirect()->back();
} 

deleting file
from database and public folder as you saved

public function delete_file(Request $request)
{
   $file = Video_Model::find($request->id);
   $file_path = $file->file_path;
   if(file_exists($file_path))
   {
      unlink($file_path);
      Video_Model::destroy($request->id);
   }
   return redirect()->back();
}
