<p>A data storage device (5) having a storage capacity of at least 8Mbyte is surrounded by a housing including a stylus portion (23), having a tip (25) for indicating a position. The stylus includes a position sensing device for generating position data indicative of the position of stylus. The stylus further includes wireless communication means for transmitting and/or receiving data for storage, and also transmitting the position data. The position sensing device may be an accelerometer. Alternatively, it may be a laser-reading head (243), for generating a signal based on received reflections from an emitted laser beam (245). The data storage device may further include an audio sensor (142, 242), and be arranged to distinguish vocal commands in the output of the audio sensor 142, 242.</p> |
