    • For providing a recording/reproducing apparatus, for recording/reproducing information through conduction of electricity upon contact of a probe, having large recording density and a large transfer speed, but less in deterioration of a probe chips thereof, and being long in the lifetime thereof, within the recording/reproducing apparatus, a multi-chip is formed, disposing probe chips in large numbers thereof at a tip of a cantilever, while the cantilever is of a double-sided beam type, and the multi-chip is disposed at a center of the beam, wherein recording/reproducing portions of the multi-chip are disposed to correspond to recording dots one by one, and the multi-chip forming surface is moved up and down in parallel with the surface of a recording medium, due to suction force, so as to bring it to be in contact with the recording dots, and electricity is conducted after the contact thereof, thereby conducting the recording, in the structure; wherein, since a large amount of data can be read/written at one time, therefore it is possible to improve data transfer speed. Also, with conducting the R/W by means of the multi-chip, comparing to the single chip, it is possible to reduce the traveling distance of the multi-chip, thereby to reduce the abrasion. Also, since the tip portion of the said chip has the curvature radius, being large, such as, equal to 50 nm or greater than that, and since it moves in parallel with the surface of the recording medium, it can be in contact with the surface under the condition of, not the point contact, but near to the plane contact, therefore, the abrasion can be further reduced, effectively.
    • 为了提供一种记录/再现装置,用于通过探针接触时的电传导来记录/再现信息,具有大的记录密度和大的传送速度,但是在其探针芯片的劣化中较少,并且在其寿命期间较长 在记录/再现装置中,形成多芯片,在悬臂的尖端处将探针芯片大量布置在悬臂的尖端,而悬臂是双面波束型的,并且多芯片设置在 光束的中心,其中多芯片的记录/再现部分被设置成一个一个地对应于记录点,并且多芯片形成表面与记录介质的表面平行地上下移动,由于 吸引力使其与记录点接触,并且在其接触之后进行电力,从而在结构中进行记录; 其中,由于可以一次读取/写入大量数据,因此可以提高数据传送速度。 此外,通过利用多芯片进行R / W,与单个芯片相比,可以减少多芯片的移动距离,从而减少磨损。 此外,由于所述芯片的前端部的曲率半径大于等于50nm以上的曲率半径,并且由于其与记录介质的表面平行地移动,所以可以与 表面在条件下,不是点接触,而是靠近平面接触,因此,磨损可以进一步降低,有效。
