depends how the disk is stuck... and the way the player drive is built.. Look for a little round hole in the front under the drive tray.. you will need a thin strong wire.. I use a straightened out paper clip.. Push it in the hole until the tray pops forward. If there is no hole often holding the eject button and powering the machine will cause the tray to open.. otherwise look in your user manual, or google the make and model for suggestions. Failing all of the above I find that dropping a player off a high building gets a disk out.. without fail
