A semiconductor wafer holder including first and second holding members between which a semiconductor wafer is held. The first coil and the second coil are in the same phase. The method includes receiving IO commands to perform IO operations on an auxiliary memory on a tape storage media device, wherein the tape storage media device includes a magnetic tape medium and does not include the auxiliary memory, and routing the IO commands to the magnetic tape medium provided in the tape storage media device. The wheel-mounting member has at least one formation for supporting an axle of the wheel. Both jack shafts can be rotated around drive shaft, where corresponding jack shafts of the gears, applied to drive shaft, are arranged one behind the other on a side of the drive shaft and where the corresponding jack shafts of the further gears, can currently be rotated around the next jack shaft.
