1. A recordable/rewritable optical disk memory content display apparatus comprising:
- an input interface under the control of a controller, for reading index data stored in a memory chip integrated with the recordable/rewritable optical disk by physical contact with input/output terminals of the memory chip, said index data representing an index of data stored in a recording region of the optical disk, wherein said index data stored in the memory chip is updated automatically through the input/output terminals when data stored in the recording region of the recordable/rewritable optical disk is changed;
a memory unit for at least temporarily storing said index data read through said input interface;
a display unit for displaying said index data stored in the memory unit or inputted thereto through the input interface; and
a controller for causing said index data read through said input interface to be stored into said memory unit, and for causing said index data to be displayed on said display unit.

Abstract
An optical disk memory content display device, system and display control method are disclosed which are capable of more quickly retrieving an index of a data for a CD-RAM. An integrated circuit memory device (Memory In Disk: MID) is integrated with an optical disk to store the index of the data on the optical disk. A reader device is, e.g., integrated into a remote control device for the optical disk read/write device, reads the index stored in the IC memory device integrated with the optical disk.

12. A method of displaying index data of a recordable/rewritable optical disk, the method comprising:
-
detecting whether input interface terminals are in contact with corresponding terminals of a memory device on the recordable/rewritable optical disk; reading, if said terminals are in contact, respectively, index data of said recordable/rewritable optical disk, wherein said index data is automatically updated through the input/output terminals when data in the recording region of the recordable/rewritable optical disk is changed; at least temporarily storing said index data; and displaying said index data. - View Dependent Claims (13)

14. A recordable/rewritable optical disk memory content display control method, the control method comprising:
-
detecting a signal from a user interface of a remote control device; judging if said signal corresponds to a display control signal; displaying, if said signal is a display control signal, index data stored in a memory of said remote control device; detecting, if no signal from the user interface is detected, whether input/output terminals of the remote control device are in contact with corresponding terminals of a recordable rewritable optical disk; reading, if said terminals are determined to be in contact, index data stored in a memory chip integrated with the recordable rewritable optical disk, wherein said index data is automatically updated through the input/output terminals when data in the recording region of the recordable/rewritable optical disk is changed; storing the newly-read index data in said memory of the remote control device; and displaying said index data of said memory of the remote control device on a display unit.
