Short Blank Cassette Tapes - Under 40 Minutes

Short-length cassette tapes - C30, C40, and C46 - use thicker tape stock than their longer counterparts. A C46 tape is typically 16 �m thick, allowing for greater magnetic coating density, better resistance to print-through, and more stable tension management from start to end. The physics favor shorter tapes: smaller hub-to-hub diameter variance means more consistent capstan torque across the entire recording, which translates to lower wow and flutter measurements.

Short tapes are also the format of choice for anyone recording to match specific source material. A C46 fits exactly one side of a standard 33? RPM LP record - preserving the original side structure and intermission that artists intentionally designed into their work. Japanese consumers, who have long prioritized minimizing blank tape waste, were the primary market for short-length cassettes, which explains why the widest variety of short tapes originated from Japanese manufacturers.

All short-length tapes in this collection are NOS sealed unless otherwise stated.
