 a drive gear formed on a periphery of the hollow cylinder to be in mesh with a second driven gear formed at an inner side of the riser such that turning the second disc will turn the hollow cylinder through the second driven gear; and   a pressing disc resiliently provided at the other end of the hollow cylinder, the pressing disc having a bottom facing the top of the tray adhered to either a cleaning pad or a polishing pad.   
   
   
       5 . The CD case of  claim 4 , wherein the platter comprises:
 a rotation hole provided on a center of the platter and located on one face of the platter facing the top of the tray wherein the rotation hole is adapted to rotatably receive a center post of the tray;   a flexible latch provided on the center of the platter and located on the other face of the platter facing the bottom of the lid wherein a center hole of the CD is adapted to securely put on the latch; and   a third driven gear formed around a periphery of the platter to be in mesh with the second drive gear.   
   
   
       6 . The CD case of  claim 5 , further comprising a hinge provided at a joining portion of the lid and the tray, the hinge including:
 two spaced first protrusions provided on one face of the lid facing the top of the tray, each of the first protrusions including a first pivot member on one side facing the first pivot member of the other first protrusion; and   two spaced second protrusions provided at one edge on one face of the tray, each of the second protrusions including a second pivot member on the other side distal the second pivot member of the other second protrusion wherein the second protrusions are fitted between the first protrusions when the lid is closed onto the tray, and the first and second pivot members are pivotably secured together for hingedly securing the lid to the tray at one edge.   
   
   
       7 . The CD case of  claim 6 , wherein the lid further comprises a peripheral flange on one face facing the top of the tray, the flange integrally formed with the lid and including:
 a well provided on one face of the flange facing the top of the tray, the well having has one face formed on one face of the lid and the other face formed on the other face of the lid, and the well adapted to receive the tray wherein the lid and the tray are formed as a unitary member when the lid is closed onto the tray;   a trough provided between the well and one edge of the lid wherein the first and second protrusions pass the trough to extend between the lid and the flange when the lid is closed onto the tray;   a cut provided on an edge at one face of the well such that the second drive gear is adapted to pass the flange to be in mesh with the third driven gear; and   at least one hole facing the other end of the actuating unit which is adapted to pass the flange for urging the pressing disc against one surface of the CD.   
   
   
       8 . The CD case of  claim 7 , wherein the flange further comprises a switch proximate the other face of the well, the switch including:
