A device for contacting and/or modifying a surface having a cantilever connected to an almost plane carrier element staying apart from said surface, said cantilever having a tip at its loose end being in close contact to said surface. It is proposed that the cantilever stand out of the plane of said carrier element. Further, a method for producing the cantilever having a tip at its loose end. The device is suitable for thermomechanical writing and thermal readout of binary information, lithographic and imaging techniques, and for surface modification.

To provide a dehumidification apparatus which can perpetually maintain the internal humidity of a disk drive low and can be installed on a cover or the like of the disk drive with a small space. Also, the dehumidification apparatus is controlled based on the internal humidity or the temperature condition inside and outside the disk drive, by which stable dehumidification can be effected without condensation etc. occurring inside and outside of the disk drive. There are provided a glass fiber which is arranged penetrating a cover of a hard disk drive (HDD) and extends inside and outside the HDD, and a heating member provided outside the HDD, so that the glass fiber on the outside is bonded to the heating member and is heated. Also, a cooling member is provided inside the HDD, and the glass fiber on the inside is bonded to the cooling member. Also, there is provided an apparatus for circulating air that is in contact with a heating portion and a cooling portion.

A scanning or positioning system with at least two degrees of freedom is provided comprising a supporting base equipped with magnets, a movable platform equipped with at least two electrical coils, and suspension elements providing an elastic connection between the movable platform and the supporting base. The electrical coils are positioned flat on the movable platform, thereby forming an essentially flat arrangement with the movable platform. Combining the flat arrangement with the flat supporting base yields a scanning or positioning system which is potentially compact, lightweight and flat and which features fast response, low power consumption and a relatively large range of motion, e.g. up to 10 mm. The scanning or positioning system with at least two degrees of freedom can be used in the field of scanning probe microscopy or in the field of data storage or imaging.
