Win32_TapeDrive class

The Win32_TapeDrive WMI class represents a tape drive on a computer system running Windows. Tape drives are primarily distinguished by the fact that they can only be accessed sequentially.

The following syntax is simplified from Managed Object Format (MOF) code and includes all of the inherited properties. Properties are listed in alphabetic order, not MOF order.
