Black Vinyl is the classic between vinyl. GZ media offers 12inch (30cm), 10inch (25cm) and 7inch (17,5cm) black vinyl.
Before choosing the format of the record, you must take the total playback time and physical principles of playback into consideration. According to this, the worst suitable format is the 7“ cut at 33 1/3 RPM. (which we don’t recommend, because this format has the lowest circumference speed during playback in the center area of the record). For the best quality sound GZ recommends 12” black vinyl with 45RPM.
