Disc read error or general issue with game?

I recently purchased half-life for the PS2 and once I reach one of the loading screens the game crashes with a black screen and when I reset the system it says disk read error it has repeatedly black screened at this pointed the game.....is there an issue with the disk or is it a genuine disk read error ? Also I saw a guide to open the system clean the lense and adjust some gear will this solve my problem?

If anyone is curious to see what the game does I have a screenshot of it and additional info it is the original fat model
