Help needed with a Dismagic 1

I have a problem with my Discmagic 1 and any help would be very welcome.

Sometimes the disc does not spin up after being inserted. Taking the case off and moving the disc round slightly often cures the problem when the payer is switched back on. Sometimes just switching the player off and on also works.

Could someone also tell me what laser assembly was used in the Discmagic and any idea of where to buy a new one and a service manual if neccessary.

Thanks for reading this.
