Abstract
An apparatus for inputting and/or outputting information includes a plurality of probes arranged at positions respectively facing each of the plural blocks which carry information, a device for enabling the plurality of probes to respectively perform tracking independently, and a device for inputting information to and/or outputting information from the information carrier by the use of the aforesaid probes.
Claims24
An apparatus for effecting at least one of recording of information on and reproducing of information from a recording medium, said apparatus comprising:
- a plurality of probes, arranged at positions respectively facing a plurality of information blocks of the recording medium, for effecting at least one of recording of information on and reproducing of information from the information blocks of the recording medium;
- displacement means for independently displacing each of said plurality of probes at least in a direction parallel to a recording surface of the medium;
- detecting means for detecting deviation of each of said plurality of probes in an in-surface direction of the recording medium relative to a predetermined path on the recording medium;
- tracking means for causing each of said plurality of probes to independently perform tracking relative to the predetermined path on the basis of the detected deviation, in order to compensate for the deviation;
- and
- recording and reproducing means comprising voltage application means for applying voltage between said probes and the recording medium for generating a tunnel current between said probes and the recording medium to effect at least one of recording of information on and reproducing of information from the recording medium.
An apparatus for effecting at least one of recording of information on and reproducing of information from a recording medium by using a probe, said apparatus comprising:
- a base plate;
- a cantilever supported at both ends thereof in a direction of its width to said base plate;
- and
- a probe provided on said cantilever.
An apparatus for effecting at least one of recording of information on and reproducing of information from a recording medium, said apparatus comprising:
- a probe, arranged at a position facing the recording medium, for effecting at least one of recording of information on and reproducing of information from the recording medium;
- moving means for moving said probe in a direction of movement along a predetermined path having a pattern preformed on the recording medium such that the direction of movement periodically reverses direction;
- detecting means for detecting deviation of said probe in an in-surface direction of the recording medium relative to the predetermined path on the recording medium;
- tracking means for causing said probe to perform tracking relative to the predetermined path on the basis of the detected deviation in order to compensate for the deviation;
- and
- recording and reproducing means comprising voltage application means for applying voltage between said probe and the recording medium for generating a tunnel current between said probe and the recording medium to effect at least one of recording of information on and reproducing of information from the recording medium along the specified path.
An apparatus for effecting at least one of recording of information on and reproducing of information from a recording medium by using a probe electrode, said apparatus comprising:
- a base plate;
- a cantilever supported at both ends thereof in a direction of its width to said base plate;
- a probe electrode provided on said cantilever;
- and
- means for applying a voltage between said probe electrode and the recording medium for generating a tunnel current between said probe and the recording medium to effect at least one of recording of information on and reproducing of information from the recording medium.
