Abstract

The tape cut-out apparatus, having: a control unit for storing a defect positional information showing a position of a defective portion of magnetic tape and, for outputting a predetermined winding length in accordance with the defect positional information; a winding device for drawing out the magnetic tape by an input predetermined winding length, winding it onto a reel and cutting it, and detecting a winding length to the reel and outputting the winding length to the control unit; and, a correcting unit for correcting the input predetermined winding length according to an accuracy of detecting the winding length of the winding device, and correcting an actually measured winding length when the magnetic tape is wound according to an accuracy of detecting the winding length and for outputting the corrected value of the actually measured winding length to the control unit.

Description

technical field [0001] The present invention relates to a tape reeling device for cutting a tape from a reel and winding its normal part as a product. Background technique [0002] For example, in magnetic tapes used for information recording, when a magnetic material is coated on a flexible support, dust adheres and defects occur due to uneven coating of the magnetic material. Such defective parts are checked at the tape roll stage. [0003] In addition, tapes used for data backup have recently recorded servo signals on the data recording surface side in advance. However, errors in the servo signals written on the tape may also become defects. Therefore, it is necessary to check whether the servo signals are written or not. defect. [0004] On the other hand, the magnetic tape which winds the magnetic tape on the tape roll is produced by winding the predetermined length on the tape control reel of a small diameter. For this purpose, conventionally, the magnetic tape is c...
