1. A hand-held pen device for recording a track of handwritten information created by the pen device, comprising:
- a device for recording said information in a digital format and a memory for storing the same, wherein the memory includes;
a first memory unit located in the pen device; and
a second memory unit located in an external data storage device, which memory units are connected in such a way that a transmission of said recorded information is caused to occur automatically from the first memory unit to the second memory unit, and through transmission of the recorded information from the first memory unit to the second memory unit, the recorded information can exceed the storage capacity of the first memory unit and thereby, from the point of view of the user the first memory unit and second memory unit form a coherent memory unit, wherein the hand-held pen device is arranged, after a “
send”
command, to send all information associated with the “
send”
command and stored in the first and second memory units to an external information management unit.

Abstract
A hand-held user unit (1), which can be part of a network-based information management system, allows for the writing down and recording of handwritten information. The user unit (1) has a memory for storing the recorded information. The memory comprises a first memory part (M1) located in the user unit and a second memory part (M2) located in an external data storage device, which memory parts are connected in such a way that, from the point of view of a user, they form a coherent memory unit.
Methods for memory management in such a user unit are also described.

14. A hand-held pen device, comprising:
-
a device for recording a track of handwritten information created by the pen device; and
an information transmission device for transferring information from the pen device, the pen device in a first memory management mode being arranged to store the recorded information in an internal memory unit and, after detection of a “
send”
command, to communicate at least a subset of the recorded information via the information transmission device,the pen device being switchable to a second memory management mode, in which the information transmission device is caused to transfer the recorded information automatically from the internal memory unit to an external memory unit in an external data storage device in such a way that by said transfer the recorded information can exceed the storage capacity of the internal memory unit and thereby, from the point of view of the user, the memory units form a coherent memory unit. - View Dependent Claims (15, 16)

17. A system for information management, comprising:
-
an information management unit; and
a hand-held pen device which is designed for recording a track of handwritten information created by the pen device, the pen device being arranged to store the recorded information in a memory and to communicate a required part thereof to the information management unit via a communication network, wherein the memory includes;
a first memory unit located in the pen device; and
a second memory unit located in an external data storage device, which memory units are connected in such a way that a transmission of said recorded information is caused to occur automatically from the first memory unit to the second memory unit, and through a transmission of the recorded information from the first memory unit to the second memory unit the recorded information can exceed the storage capacity of the first memory unit and thereby, from the point of view of a user, the first memory unit and the second memory unit form a coherent memory unit, wherein the external data storage device comprises a network server with an interface that allows a user of the pen device to access the recorded information. - View Dependent Claims (18, 19, 20, 21, 22, 23)

24. A method for providing memory capacity for a user of a hand-held pen device which is designed for recording and communicating a track of handwritten information created by the pen device, comprising the steps of:
-
reserving memory capacity for the pen device in an external data storage device;
receiving, automatically, recorded information from a memory located in the pen device and storing the same in the external data storage device, and sending the recorded information to an information management unit in response to a “
send”
command. - View Dependent Claims (25, 26, 27)

28. A method for memory management in a pen device, which is arranged to record a track of handwritten information created by the pen device, comprising the steps of:
-
storing the recorded information in a first memory unit in the pen device;
transferring at least a subset of the recorded information from the first memory unit to a second memory unit in an external data storage device in such a way that a transmission of said recorded information is caused to occur automatically from the first memory unit to the second memory unit, and the recorded information can exceed the storage capacity of the first memory and thereby, from the point of view of a user, the first and second memory units form a coherent memory unit, arranging the hand-held pen device, after a “
send”
command, to send all information associated with the “
send ”
command and stored in the first and second memory units to an external information management unit.
