This is a somewhat out of focus R202 card with four diodes desoldered for replacement. When they originally installed the components they bent the leads over to hold them in the board for soldering. This makes removing the components more difficult. If you're confident cutting the leads off the component and then removing them is easiest and least likely to damage the board. I've made enough mistakes that I don't use that method.
I use my desolder tool to remove most of the solder then if the lead won't easily come loose remove more with solder wick. Extra flux can help. If the lead still isn't loose for transistors you can press down a little while heating and the lead will normally lift off the pad. That doesn't work for diodes. For them I grab the lead with the diagonal cutters and wiggle/twist slightly to free the lead. Don't use excessive force or pry up or you will likely lift the pad off the board. If it still doesn't come free back to the solder wick pushing the lead a little on the pad.
Keep the soldering iron on the pad. If it touches the board it may leave a mark. Also excessive heat can lift the pad. After the lead is free I straighten it with my diagonal cutters then remove the part. Since the holes aren't plated through only the portion of the lead on the pad is attached by solder.
The tape is a label with the symptom from troubleshooting the computer and the location the card came from.
