Abstract
The universal data storage element presents a of uniform form factor that enables the user to vary the contents to include a selection of media types to provide variable data storage and/or recording characteristics. The physical characteristics of the media located within the data storage element are identified by a coding arrangement located on the exterior housing of the data storage element. The data storage element self identification apparatus consists of a plurality of coding apertures arranged in a linear array and located along one edge of the exterior housing of the data storage element. These coding apertures are placed as a function of the type of media contained within the data storage element or various data management characteristics of this media. The coding apertures are implemented by inserting a block into a corresponding recess in the front of the housing. One of the apertures is manually definable by a slide mechanism to enable a user to set the write protect status of the media. A human readable mark is also provided on the slide mechanism to indicate the write protect state of the media. The insertable block can be color coded to provide a human readable defi…
