The average 3T Pit Jitter values for all recording speeds are illustrated in the following graph. None of the above tested media gave back C2 errors and all C1 values are in low levels. The total errors pending the reading process were only During the playback of the fifth level the memorx of the track playback was smooth not more than one time.

Memorex True 8X Dual Format – DVD±RW drive – IDE – internal

The “plus” format uses a more reliable bi-phase modulation technique [4] to provide ‘sector’ address information. During the test, no errors such as muted or skipped sequences were reported and only the As for the CD format, the 24x writing speed was supported with all media we tested, although this was expected for an average writing speed.

Archived from the original on On the above graph we can see that the Nec is the fastest among the three drives on the DVD ripping test. Just like the data pressed discs we tested before, the software reported high seek times with Full seek at ms. As trrue-8xthe market for recordable DVD technology shows little sign of settling down in favour of either the plus or dash formats, which is mostly the result of the increasing numbers of dual-format devices that can record to both formats.


Just like the previous Pit values measurements, the Ritek disc gave back the highest Land Jitter value, 35ns, while the Fuji disc gave the most stable measurements.

In the following graph you can see the recording times with various media brands. The larger storage capacity of a DVD-R compared to a CD-R is achieved through smaller pit size and smaller track pitch of the groove spiral which guides the laser beam. The beginning of the second layer is located in the outer part of the disc, so the drive starts reading from the outer tracks inwards towards the inner tracks of the disc.

Memorex True-8x

These specifications were confirmed by Nero CDSpeed. For checking the drive’s EFM correction status, we used 4 different game titles with different SafeDisc 2 and SafeDisc 3 versions having the latest software patches installed. Trye-8x Buffer Underrun Protection: On the quick erase testMemorex proved to be 4sec faster than Pioneer. Memorex supports both minus and plus format for DVD writing.

The groove on a DVD-R memodex has a constant wobble frequency used for motor control, etc. On the reading part Memorex read all discs we tested without encountering any problems. The drive finished all tests and therefore the average error correction score of the drive is good. Because of this shorter wavelength, DVDs use different dyes from CDs to properly absorb this wavelength.


According to the graph, Memorex True-8x started the writing process at With protected game titles, Memorex didn’t true-8d any working backups. Only Nec managed to read and rip the contents of both protected discs. Newegg keeps the Black Friday spirit alive with more memorxe for Cyber Monday.

Nec was about one minute faster because it supports 32x maximum writing. After making the images of the various titles to the hard disk, we burned them maximum speed using CloneCD.

Memorex uses the RPC II region control, allowing a user to change the drive’s region at most 5 times. Depending on the intensity of the laser, the tfue-8x property of the dye on a particular spot will determine whether it is a peak or a valley representation from pressed DVD.

Twitter’s Ad Sales Surge. Below are the best writing times at all available writing speeds of all three drives. It also has 65 – 75 micrometres high fingerprints.
