Diskdrive Will not Aceept Disk

Greetings. I am a novice when it comes to Macbook. I have purchased a MacBook Pro A1278 - Mid 2010 from a yardsale in my area for very cheap. Of course, the cheap price came with issues. Aside from a cracked screen, I am unable to use the disk drive. The drive will not accept any disk.

Through reaseach, I have found that I need to replace the "SuperDrive." After looking for a replacement part, I have found several model numbers. Can anyone assist me in finding the right part and even a DIY tutorial?

The last 3 characters of my Serial # are ATM.

Thank you in advance.
