Overview

The Sony 10MC-90B is a 10-pack of 90-minute blank microcassettes designed for use with standard microcassette recorders and transcription machines. Each cassette delivers 45 minutes of recording per side at normal speed, making them well-suited for dictation, interviews, meeting notes, and voice memos. As genuine Sony products, they are manufactured to the same quality standards that made Sony a long-standing name in magnetic recording media, ensuring consistent tape tension, smooth transport, and reliable playback across compatible hardware.

All 10 cassettes arrive new and factory sealed, guaranteeing they are unused and free from prior recordings. For professionals, legal offices, and medical practices that continue to use microcassette-based dictation systems, this bulk pack provides a convenient, cost-effective way to keep a ready supply of blank media on hand without the need for frequent reorders.
