An arrangement is described for reading information from and/or writing information to a sheet of flexible sheet material. A platen supports the sheet in a curved configuration across its width such that its first surface is inwardly oriented with respect to a curved configuration to define a tubular shape having lengthwise edges of the sheet positioned in a confronting relationship. An actuator moves the sheet in a direction along a lengthwise path oriented at least generally along the length and transverse to the direction of curvature, but without rotation about the lengthwise path. At least one of a read head and a write head, which can be fixed in the direction of movement along the lengthwise path, performs at least one of reading and writing information widthwise across the surface of the sheet as the sheet is moved along the path. |
