A method for fabricating an electroluminescent display and the substrate and apparatus used therein. The display is preferably constructed on a pre-constructed substrate that includes a flexible base layer having a conducting surface on one side thereof. The base layer is impermeable to oxygen and water. The substrate includes a plurality of wells defined by a barrier layer, each well having an electrode layer connected electrically with the conducting surface. A removable protective layer covering the wells protects the electrode layer from attack by oxygen and water prior to being utilized to make the display. In one embodiment, each of the wells also contains an electron transfer layer in contact with the electrode layer.

Disclosed is an apparatus and method for defining magneto-optical disk media and an optical data storage device that allows the media to be convertible from writable to read-only. The media has a media descriptor table contained within a control track which is modified to define the media as a new media type. Previously manufactured drives will not recognize the media type, and therefore, will not read or write the media, so the data on the media is protected from being destroyed by such drives. The invention also defines a storage state bit within each sector of each track of the media, that defines whether the sector is writable or read-only. With this bit set into the writable state, the sector can be written many times. Once the bit is changed to read-only, however, the sector can no longer be written. The data storage device of the invention will not reset the bit, once it is set to the read-only state.

The base layer is impermeable to oxygen and water. The substrate includes a plurality of wells defined by a barrier layer, each well having an electrode layer connected electrically with the conducting surface. A removable protective layer covering the wells protects the electrode layer from attack by oxygen and water prior to being utilized to make the display. In one embodiment, each of the wells also contains an electron transfer layer in contact with the electrode layer. The electron transfer layer includes a material that improves the efficiency of the injection of electrons from the electrode layer into the electroluminescent layer of the display. This display is fabricated by moving a first dispenser relative to the substrate so as to quantitatively deposit a first electroluminescent material on the substrate, different amounts of the first electroluminescent material being deposited at different locations on the substrate in response to signals defining an illumination pattern to be generated by the display.

A digitizing pen has a pen body with a writing tip for handwriting on a sheet of paper. An optical sensor disposed in the pen body images a writing surface of the sheet of paper. A tag-recognition reader is connected to the optical sensor, and gathers location information from data encoded on at least one tag positioned on the writing surface. A velocity reader is connected to the optical sensor, and gathers speed and relative direction information of the writing tip over the writing surface. A processor connected to receive the tag location, writing-tip speed, and writing-tip relative direction information, can then compute a series of locations on the writing surface visited by the writing tip.
