Abstract
A magnetic recording disc-jacket assembly within which a magnetic recording disc is positioned includes a jacket having a central window for receiving a drive shaft and an elongated head window for receiving a recording/reproducing head. A cleaning liner made of fibrous material is disposed at each side of the disc within said jacket and is bonded to the jacket at heat bonding portions. The fibrous material is heat pressed so as to have a reduced thickness adjacent the cut edges for the respective windows of the liner to prevent fraying of the fibrous material.
