Star Trek Tricorders: Data Storage Capabilities Throughout the Series
Perhaps the most iconic piece of technology from the Star Trek universe is the Tricorder, a handheld device used for a variety of functions ranging from scientific analysis to data storage. Curiously, the capacity of these devices varies significantly over the years, due to advancements in technology and the specific needs of the characters using them.
Tricorder in Kirk's Time
In the original series and its predecessors, the most common Tricorder model used was the TR-114. The TR-114 was a self-contained suite of sensing, recording, and analysis functions that had limited memory in its basic unit, but it could be expanded with multiple shielded ROM modules.
ROM Modules and Memory Limitations
The memory in the TR-114 could be enhanced by mounting up to eight special shielded ROM module disks simultaneously. These disks, located beside the primary sensor cluster, provided Gigaquads (GQ) of memory. The standard memory partition for each disk was approximately 500 GQ, which was deemed sufficient for recording data in those days, as hand-held sensors did not have very high resolutions or data loads. This capacity translated to around 72 hours of basic high-fidelity 1080p video recording.

Specialized Models and Microtapes
Some specialized Tricorders, like the TR-116 or the United Press Variant TR-113, came equipped with antennae that could transmit sensor data to a central interpolation unit, allowing for complex scientific data collection. These specialized Tricorders used Microtapes for data storage, which typically had a capacity of 250 GQ.
Tricorder in Picard's Time
The more advanced Tricorder model used by Jean-Luc Picard and his crew was the TR-560. These new tricorders operated differently from their predecessors. They no longer relied on the slow and vulnerable Duotronic relays; instead, they featured Isolonear circuitry, which was both faster and more versatile in processing speed and memory capacity.
Advanced Technology and Internal Memory
The standard Tricorder TR-560 boasted an impressive 0.9 Teraquad (TQ) of internal memory, which was a significant leap from the 500 GQ of the TR-114. However, the TR-560's capabilities were amplified by its ability to connect to the ship's primary library computer.
Accessing Ship Data and Subspace Capability
By linking to the ship's computer, the Tricorder could access and compare data streams from the ship's sensors, doubling its versatility. This integration also allowed the Tricorder to request data from the ship's computer using subspace carrier waves. When within 400,000 kilometers, the Tricorder's capabilities multiplied, effectively becoming a tool with virtually limitless memory and processing power.
Field-Utility Features
The TR-560 also included more advanced field-utility submodules. One such feature was the ability to act as a sensor/communications hub for away teams and security units. By using the "Pool" command, multiple Tricorders could be linked together to create an extended sensor coverage area, making it invaluable for tactical and scientific missions.
Conclusion
The evolution of Tricorders from Kirk's era to Picard's showcases significant advancements in technology and functionality. While the TR-114 was limited by its design and memory capabilities, the TR-560 ushered in a new era of data collection and analysis, making it a versatile and powerful tool for Starfleet missions.
