Digital Talking Book Cartridge
Audio file for Digital Talking Book Catridge
The player plays DTBs stored on USB flash drive cartridges. These cartridges contain a type
of solid state memory that is nonvolatile and can be rewritten thousands of times. They are
resistant to damage by extremes of temperature, humidity, and other environmental conditions
expected to be encountered by patrons and libraries.
The cartridge has a feature that enables erasing or rewriting of the contents, but only by
authorized parties. Thus, it is impossible for patrons to inadvertently or maliciously alter
the contents of the book.
Cartridges accommodate a print and braille label in a slightly recessed area to protect the embossed
braille. This label contains two 30-point print lines, four large-print (14-point) lines, and five
rows of book information in braille. The underside of the cartridge has an area available for a
library-specific label or identifier.
The cartridge has mechanical features that assist handling by physically handicapped persons. It can be
inserted into the player in only one orientation.
