Hithub GrooveDisc — Standard Play Funk Compilation CD

The Hithub GrooveDisc Standard Play Funk Compilation CD compiles eighteen essential funk recordings across seventy-four minutes of maximum CD capacity, mastered to the Red Book standard at 44.1 kHz and 16-bit resolution from high-resolution digital transfers of the original multi-track session files, delivering the full dynamic impact of the genre’s most influential producers and arrangers in a format optimized for both home playback and DJ mixing use. The disc is manufactured on a polycarbonate substrate of 1.2 mm thickness, produced at an injection speed calibrated to achieve a birefringence measurement below 20 nanometers across the full disc radius, a quality benchmark that ensures consistent laser tracking performance across all compliant CD players manufactured since 1982. The aluminum reflective layer is deposited by magnetron sputtering to a thickness of 65 nanometers with a reflectivity coefficient exceeding 70 percent across the 780-nanometer laser wavelength, meeting the Red Book Disc Specification Section 4.2 reflectivity requirements with a 5 percent margin. The lacquer protective coating over the data layer is applied by spin coating at 2,000 revolutions per minute to achieve 10-micron uniform thickness. The jewel case uses a 6 mm hinged shell in optical-clarity polystyrene with a 36-page booklet printed on 130 gsm silk coated stock featuring full-color artist photography and detailed recording session notes.
