。[Claims for Utility Model Registration] 1. A cylindrical guide drum that spirally winds and guides a magnetic tape, and a magnetic head that protrudes from the outer peripheral surface of the guide drum and rotates to form signal tracks on the magnetic tape. A cylinder device for a magnetic recording and reproducing device, comprising: a fixed guide drum; and a solid lubricant layer formed on the tape running surface so that the thickness gradually increases from the entrance side to the exit side of the magnetic tape. 2. Set the center of rotation of the magnetic head relative to the fixed guide drum at the center of the first fixed guide drum axis before the solid lubricant layer is formed and the second fixed guide drum axis after the solid lubricant layer is formed. A cylinder device for a magnetic recording/reproducing device according to claim 1.3 A utility model registration claim in which the amount of wear of the solid lubricant layer is equal to the amount of wear of the magnetic head. 1st
A cylinder device for a magnetic recording/reproducing device according to item 1 or 2.
