RIVER DVD-R Silver Thermal Prism – Full Surface Printable – 4.7GB 16× (100 Pack)

River DVD-R Silver Thermal Prism – Professional Grade Media

River DVD-R Silver Thermal Prism discs are part of the River Media professional range, developed for users who require dependable performance and consistent results in thermal printing and duplication workflows. The silver lacquer thermal printable surface delivers clean, professional output and is suitable for use with most thermal disc printers.

Manufactured using purple azo-based recording dye, these DVD-Rs provide stable burning performance, broad playback compatibility, and dependable long-term storage. The write-once DVD-R format ensures data integrity, making the discs suitable for video, data distribution, and archival use.

Designed for recording speeds of up to 16×, River DVD-R Silver Thermal Prism discs offer efficient performance for both manual and automated duplication systems.

Precision Engineering for Superior Recording

Unlike stamped DVDs, DVD-R media is manufactured with a continuous spiral groove, similar in concept to a vinyl record. This groove — known as the pregroove — provides a highly precise track for the writing laser to follow during recording.

DVD players rely on accurately tracking the spiral path of recorded pits in order to read data correctly. Any deviation in this path can affect playback reliability.

A slight, controlled wobble is built into the pregroove using a pre-established pattern. This wobble generates a frequency used as a carrier signal, supplying essential timing information that regulates:

• Servo motor control
• Laser tracking accuracy
• Focus of the laser beam

In addition, land pre-pits moulded into the disc substrate provide address information and pre-recorded data, enabling precise initiation of the write process.

Advanced DVD-R Write Strategy

DVD-R recording requires a significantly more complex write strategy than CD-R media. The recorded pits on a DVD-R are approximately half the size of those found on a CD-R, and the spacing between pits and lands within the spiral data pattern is considerably tighter.

This increased density demands exceptional manufacturing precision to ensure accurate pit formation, stable recording, and reliable playback across a wide range of players.

What Makes River Media DVD-Rs the Professionals’ Best-Kept Secret?

Error correction performance is a critical measure of disc quality. In DVD media, error rates are measured using:

• PI (Parity Inner)
• PO (Parity Outer)

Unlike CD media — where uncorrected C1 errors escalate to C2 errors — an uncorrected PI error in DVD media becomes the far more serious PO error, which can directly impact data integrity and playback reliability.

River Media DVD-Rs are the result of many years of manufacturing refinement and technical expertise. Their exceptionally low PI/PO error rates deliver performance that consistently outperforms leading competitors, as demonstrated in comparative scan results.
