Reply to Discman as Jogwheel

I don't have money for expensive technics turntables or fancy USB Jogwheels so i want to build my own jogwheels. Not for scratch purposes, just for searching through tracks

I got the idea when i found my 2 old discmans, and then i thought that i maybe could use those, to build my jogwheels. My idea was to replace the laser from a optical mouse, with the one in the discman and then connect the discman to my MacBook with the USB cable from the mouse. My Mac will then recieve data when i spin the CD on the Discman, (above the laser) but the only problem is that i don't know how to "convert" the data my Mac is getting from the mouse, (the laser from the mouse which i had put into the discman)to midi signals.

i would really apreciate some help, because it feels like i'm standing a few milimeters from my goal and can't reach it because there's a little obstacle in my way.

Do you know how to di it? or do you have a better/easier way to make my own jogwheels? All help is welcome
