my cd transport hungry for new music ?

Last night after listening for the first time to a cd of electronic music by Olafur Arnalds, I stopped play and then also by remote opened the tray,  BUT ...

no cd.  Empty tray. I'd just been playing a cd for sure  - not streaming -
 yet it was gone.

Retracting and opening the tray, I heard the disc rattling around inside the player.
Finally it stopped, having found its own resting place. 

Problem is, it's a cd borrowed from the NYPL and has to be returned or I'm liable for $50 replacement fee.
Reluctant  to return the unit to Boucherville, Quebec,   I'm wondering
  if there's any way to extract the disc from the player ?
The transport continues to play other discs, but it must have really  loved the Arnalds. Snapped it right up.
