Blank Media

Blank Media

Get to know all the types and formats of blank CD-R, DVD-R and Blu-rays.

CDs come 100 per spindle and 400 per case. DVDs come 50 per spindle and 200 per case
Paper Sleeves are 0.05/ea and come in a case of 1000
Generally an order is filed and shipped the same day it arrives.
That depends on the quantity desired and if they are inkjet or thermal, white or silver.
We generally request a credit card if orders are 500.00 or less and we will open a credit account for orders in excess of 500.00 billed on a NET 30 term.

Burning a CD using a burner(writer) with a writing speed of 4X will take about twice as long as burning the same CD using a burner with a writing speed of 8X. Usually A CD burner(writer) with a higher writing speed is more expensive than the one with lower speed.

The X refers to disk capacity. The capacity of the first 3.5" optical disk released was 128 MB. The capacity of newer, higher capacity disks are expressed as multiples of the first released disks. The latest 3.5" 5X media has a capacity of 640 MB, five times the capacity of the 1X 128 MB.

By design, ISO standard optical drives are downward compatible. At a minimum, 3.5" Optical drives are read and write compatible one level down and read compatible two levels down. Since the highest generation 3.5" drive is 5X, these drives will read 1X-5X media and write to 2X-5X media. Most drives in production now are read/write compatible with all 3.5" media.

The pregroove wobble is at a higher linear frequency (cycles/cm.) on the 74 minute blanks, causing the recorder to spin the disc slower (74 min: 1.2 m/s vs. 60 min: 1.4 m/s) and thereby record more information in the same linear space. The 80 minute discs are made by decreasing the track pitch (i.e. space between tracks) from the MD standard's 1.6um to 1.5um (micrometers), the minimum allowed by the MD specification; like the 74' blanks, they also run at 1.2 m/s. There is also information... Read more

MiniDiscs were announced in 1991 by Sony as a disc based digital medium for recording and distributing consumer audio that is "near CD" in quality. In 1993 Sony announced MD Data, a version of the MiniDisc for storing computer data.

There are two physically distinct types of discs: Premastered MDs, similar to CDs in operation and manufacture, and Recordable MDs, which can be recorded on repeatedly and employ magneto-optical technology. The disc itself is enclosed in a small... Read more

Generally DVD calls as:
1 KB = 1000 B, 1 MB = 1000 KB, 1 GB = 1000 MB
Computer calls as:
1 KB = 1024 B, 1 MB = 1024 KB, 1 GB = 1024 MB
Therefore, with a PC,
4.7 GB = 4,7000,000,000 Byte / 1,024 = 4,589,843 KB
4,589,843 KB / 1,024 = 4,482 MB
4,482 MB / 1,024 = 4,376 GB
Which is nearly equal, 4.38 GB (a capacity shown will depend on the software)
Both of them has quite same capacity but each of them has different unit, 1000 or... Read more

It should be possible to achieve playback on many DVD players and DVD-ROM drives, barring some exceptions. Formats released by the DVD Forum are specifications for the MEDIA only.
Although a recorded DVD-R disc falls within the same specifications as DVD-ROM (DVD-VIDEO), because the formats are media-related ONLY, support will be entirely up to the hardware maker. According to a study conducted by media makers, DVD-R media is capable of playback on many players with some... Read more

DVD-RAM, with an initial storage capacity of 2.58 billion bytes, later increased to 4.7, uses phase-change dual (PD) technology with some magneto-optic (MO) features mixed in. DVD-RAM is the best suited of the writable DVD formats for use in computers, because of its defect management and zoned CLV format for rapid access. However, it's not compatible with most drives and players (because of defect management, reflectivity differences, and minor format differences). A wobbled groove is used... Read more

DVD-RW (formerly DVD-R/W and also briefly known as DVD-ER) is a phase-change erasable format. Developed by Pioneer based on DVD-R, using similar track pitch, mark length, and rotation control, DVD-RW is playable in many DVD drives and players. (Some drives and players are confused by DVD-RW media's lower reflectivity into thinking it's a dual-layer disc. In other cases the drive or player doesn't recognize the disc format code and doesn't even try to read the disc. Simple firmware upgrades... Read more
