Abstract

Removable storage media, such as magnetic tapes and optical disk cartridges, must be protected from dirt and other contaminants when not inside the host device (tape drive, optical drive, or library). Environmental protection is also required for more-advanced removable storage components which includes but is not limited to removable hard disk drives and solid-state memory devices. In essence, any removable component used for data storage should have a protective case or sleeve to prevent or reduce contamination when located outside the storage device in which it is used. This ensures more reliable performance by protecting both the media and storage device from deterioration caused by dirt and other contaminants.

Anti-static sleeves for storage cartridges and removable media

   Removable storage media, such as magnetic tapes and optical disk cartridges, must be protected from dirt and other contaminants when not inside the host device (tape drive, optical drive, or library). Environmental protection is also required for more-advanced removable storage components which includes but is not limited to removable hard disk drives and solid-state memory devices. In essence, any removable component used for data storage should have a protective case or sleeve to prevent or reduce contamination when located outside the storage device in which it is used. This ensures more reliable performance by protecting both the media and storage device from deterioration caused by dirt and other contaminants.

In the past, protective sleeves and cases have been designed with no precautions against another type of environmental condition. This condition is the accumulation or generation of static charges on the removable cartridge or component. Insertion of these charged cartridges or components can disrupt operation of the host device, and in some cases, cause permanent damage to electronics. In the case of removable magnetic tape or optical media, the host drive or library operation may be temporarily or permanently affected but generally would not result in permanent data loss or corruption on the media itself. However, for more complex removable components like hard disk drives, there is the potential for this permanent data loss to occur if no attention is paid to elimination of static electricity.

An actual example of protective cartridge sleeves not preventing, but actually creating, the generation of static electricity can be found with the optical media used in the IBM 3995 Optical Library Dataserver. These 5.25-inch re-writable or WORM cartridges are placed in protective sleeves when shipped or stored outside the drive or library. These sleeves are typically made from a stiff paper material with no static dissipative properties, and they tightly enclose the cartridge to minimize entry of dust and dirt. Removal by...
