Abstract: Information is prevented from being retrieved by an unauthorized person when an information processing apparatus is stolen or lost. There is provided an information processing apparatus including: a storage; dividing logic/utility that divides data stored on the storage into a predetermined first number of pieces of partial data; transmitting logic/utility that transmits one or more of the first number of pieces of divided partial data to one or more different information processing apparatuses, and deletes the one or more of the first number of pieces of partial data from the storage; retrieving logic/utility that retrieves the one or more pieces of partial data from the one or more different information processing apparatuses, and stores the retrieved pieces of partial data onto the storage; and restoring logic/utility that restores the data from the minimum number of pieces of partial data.

Abstract: A single driving system (4, 5, 6) is provided for a plurality of pairs of controlled systems and axis controllers (1, 12:2, 13). This driving system is connected to a required pair of the controlled systems and the axis controllers as needed using an axis changing device (3) and a changing controller (7). At this time, the shaft position data of the driving system, at the time when a controlled system is separated from the driving system, is stored in a first axis shaft position data storing device (8) or a second axis shaft position data storing device (11). When the connection is returned, an offset signal is sent to the changing controller (7) from a first axis shaft position offset calculator (9) or a second axis shaft position offset calculator (10). Thus, a plurality of controlled systems can be driven by a single driving system.
