Method for reducing occurrences of tape stick conditions in magnetic tape

a technology of magnetic tape and occurrences, which is applied in the direction of moving record carriers backward/forward, mechanical tension control of carriers, instruments, etc., can solve the problems of tape sticking or breaking, tape sticking or falling, and the tendency of the drive to drop tension, so as to reduce the occurrence of tape stick conditions, and the effect of dropping tension

Abstract

Disclosed is a method for reducing occurrences of stick conditions in tape, the method including stopping rotation of a supply reel and take-up reel of a drive that includes a length of tape, a portion of the tape extending between the reels and contacting a head between the reels, wherein the stopping creates a stop condition in the drive, determining if the tape is stuck to the head, dropping tension in the tape between the reels, freeing the tape for movement in a z-direction via the dropping tension, moving the head in y-directions, moving the tape in an x-direction via a rotation of the supply reel a fraction of a rotation, and causing the tape to break contact with the head via the dropping, moving of the tape in the z-direction, moving of the tape in the x-direction, and / or moving of the head in the y-directions.

Description

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The disclosure relates generally to a method for reducing occurrences of tape stick conditions in magnetic tape, and more particularly to a method for reducing occurrences of tape stick conditions in magnetic tape disposed in a reel-to-reel tape drive.

[0003] 2. Description of Background

[0004] As linear and track densities are increased for magnetic tape in reel-to-reel tape drives, it becomes desirable to have smoother and smoother media. Smoother media leads to more frequent occurrences of adherence between the tape and magnetic heads of the drives, especially in humid conditions. This is caused by the “Jo-block” effect, wherein two smooth surfaces are rubbed against each other squeezing out any lubricating air interface and causing the two smooth surfaces to stick.

[0005] Once the tape sticks to the head, the drive tends to drop tension because it cannot move the tape. This leaves the drive with stuck or broken tape, whic...
