1. A pen system for recording a track of handwritten information, said system comprising:

  • (A) a handheld pen device comprising;

    an image sensor for optically sensing a position-coding pattern printed on a surface, said position-coding pattern identifying an identity of the surface;

    a processor for decoding imaged portions of the position-coding pattern and generating digital ink representative of the track of handwritten information and the identity of the surface; and

    a first memory unit, located in the pen device, for storing said digital ink; and

    (B) a second memory unit located in an external data storage device,wherein said pen device and said second memory unit are connected in such a way that transmission of said digital ink is caused to occur automatically from the pen device to the second memory unit, and wherein receipt of said digital ink by said second memory unit causes said second memory unit to associate the track of handwritten information with a stored description of said surface, said stored description corresponding to said surface identity.
