SQ Series: Highly Reliable Professional Tape with Low Error Rate

Low Error Rates Due to Careful Tape Screening

Panasonic's SQ-Series tapes are screened using highly stringent error rate standards in order to minimize errors. This gives them the high-quality image and sound recording capability that is demanded in tapes for professional use.

Error Rate Distribution Comparison

High output level from a 4x density tape

The magnetic particles on SQ Series tapes are coated with four times the density of previous tapes, using a unique high-density deposition technology developed by Panasonic. This gives them the industry's top level of output, and makes them ideal for recordings that simply cannot be re-shot, such as wedding ceremonies and other important events.

High Output Level

High Density of Magnetic Layer

Structure Model

Toughness/1,000 times recording

Maintain high quality recording even after 1,000 times.
Suitable for repeated heavy use by recording, editing, copying.

Durability Test

Tough cassette with anti-static lid

The precision engineered cassette shell is molded of ABS resin, which prevents warping and provides tough impact resistance and durability.
The anti-static cassette lid treatment repels dust, debris, and contaminants, minimizing dropouts. A paper label comes already affixed, allowing for quick and easy writing.


2-way opening soft case

A soft material that won't break if dropped is used for the cassette case. The 2-way lid construction lets you easily extract the tape with one hand, even while shooting.
