Abstract

PURPOSE:To prevent the generation of a permanently folded part on a magnetic tape at a failure in threading, by providing air blowout holes on a magnetic tape guide suface opposing to a vacuum column and putting the tape in the vacuum column through the blowout of air to the tape. CONSTITUTION:The supply of air to an air blowout hole 9 is stopped at first and a file 1 is rotated to lead off a magnetic tape for threading. The tip of tape reaches a machine reel while being introduced with a negative pressure formed with an air flow from an air blowout hole 8. During this operation, when the tip of magnetic tape arrives at the vicinity of a contact point between an outlet side air bearing 6 and a tape guide surface 7, air is blown out of the hole 9. If the threading is failed and the tip of tape does not reaches the machine reel, excessive tape led off from the reel 1 suspends in a vacuum column 4 with the air flow blown out of the hole 9, thereby avoiding the formation of an S- loop of tape in a winding body 2.

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a tape guide device such as a magnetic tape device, and particularly to a tape damage prevention mechanism thereof. In storage devices, the magnetic f-7' is passed from the 7-isle φ reel to the machine reel, and a buffer device such as a vacuum column is used to form a magnetic tape buffer loop before normal operations such as reading and writing data are performed.

Threading involves unwinding a fixed length of magnetic tape from a file reel, and using airflow to thread the tip of the tape into a machine.
This is done by guiding it to the reel side,
In order to rethread the tape, the spinner must rewind the unwound magnetic tape onto the pull reel. At this time, if the magnetic tape loops that were supposed to have been fed out are made and overlapped, they may be folded into the inside of the tape, causing a permanent bend in the cloudy magnetic tape. This makes threading difficult near the leading edge of the magnetic tape, and if this bent part is a data recording part, it can destroy the data or make writing or reading impossible.

To achieve the above object, the present invention provides a magnetic tape device such as a mass storage device. An air blowing hole is provided on the magnetic tape guide surface facing the column, and air is constantly blown so that when threading fails, the unwound magnetic tape converges in the middle of the vacuum column. When the leading edge of the magnetic tape passes through this, it is guided towards the vacuum column by this air flow and does not reach the other reel ray and the original auto-threading is not performed, so the leading edge of the magnetic tape passes through the air blowing hole, Further, after the vehicle has traveled a certain distance, a means is provided for blowing out air from the air blowing hole.

Therefore, even if the threading is re-threaded, permanent bends will not occur in the magnetic tape as described above. The rotation angle of the above-mentioned Jinfu E. Lee A; 1 is measured by a rotation angle meter already installed in the file reel 1. In addition, the timing to open the valve 12 is controlled by the control combination 2 built into the magnetic tape device along with the control for threading, so it is only necessary to change a part of the program. The air flow supplied to the first air outlet 9 can be obtained via a valve from an air flow source (not shown) supplied to the first air outlet 8, so a special pump or the like is required. There is no need to prepare anything.
