DEC-TK50-CompacTapeSubsystem

The Digital TK50 CompacTape Cartridge Subsystem is a high-capacity, reliable, and compact tape drive designed for microsystems, primarily for backing up Winchester disks and for software distribution.

Key Features & Benefits:

• Capacity & Performance: Offers 95 Mbytes of formatted capacity on a single half-inch tape cartridge. It supports streaming at 75 inches/second, with user data transfer rates up to 45 Kbytes/second, enhanced by a 16 Kbyte write-through cache for improved performance and data integrity. Data is recorded on 22 tracks in a serial serpentine pattern at 6667 bits/inch.
• Data Integrity: Ensures exceptional data protection through read-after-write verification, Cyclic Redundancy Check (CRC) for on-the-fly error detection, and a powerful Error Correction Code (ECC) capable of correcting significant data errors. The drive's gentle tape handling and precise control also contribute to reliability.
• Reliability & Maintainability: Features a simplified mechanical and electrical design with fewer, rugged parts and microcode control for high reliability. A significant advantage is that it is a maintenance-free product, requiring no field adjustments or head cleaning.
• Compatibility & Support: Compatible with all Digital's current Q-bus and UNIBUS systems, including MicroVAX and MicroPDP-11. It's supported by the Tape MSCP protocol across Digital's 16- and 32-bit operating systems, making it easy to integrate and use familiar tape commands. It also facilitates data and program transport between different Digital systems.
• Ease of Use & Installation: Its compact 5.25-inch form factor (similar to a mini-floppy drive) allows it to fit into standard microsystem enclosures or be packaged as a standalone tabletop or rackmountable unit. Operation is straightforward with automatic tape threading, and it includes built-in diagnostics for easy problem identification.

The TK50 combines Digital's reputation for reliability, compatibility, and performance with a compact size and low cost, making it an essential and valuable high-capacity data storage solution for microcomputer environments.
