HPG dishes on discs

DVDs and CDs are ubiquitous now, but not so long ago they were a new phenomena that stormed the media world and reinvented the way we listened to music and watched videos.

The Compact Disc (known as a CD) was originally developed in 1982 to store and playback sound recordings in digital data form, the format was later expanded to encompass data storage (CD-ROM), one-time audio and data storage (CD-R), rewritable media (CD-RW), and others. In 1995, the DVD was invented, offering visual media storage and offering a higher capacity than compact discs.

Here is a chart of how much capacity each disc type holds:

  • CD: Capacity 700 MB or 70 min
  • Dvd5: Capacity  4.7GB or  120 min  (Single Side, 1 Layer)
  • Dvd9: Capacity  8.5 GB or  230 min  (Single Side, 2 Layers)
  • Dvd10: Capacity  9.4 GB or  250 min (Double Sided, 1 Layer per Side)

Pre-recorded DVDs and CDs are mass-produced using molding machines that physically stamp data onto the discs. The entire process is fascinating.

We offer replication services for all types of discs as well as insert them into mailers, bind them into sleeves for both perfect bound and saddle stitched magazines and books, print labels and jackets, and include them in just about any printed piece you can imagine.
