You are not measuring “disc errors”, but “read errors”. What you are seeing is a marginal CDR that will sometimes read without errors, and sometimes not. If you check it in different drives you will also see differing results. Even the slightest smudge will also cause read errors, so each test may look different.
My interpretation of this is that you need slightly better media or a slower burn speed. A really good CDR will show no errors every time, and will read at full speed.
