LARGE buffer or cache, as in multiple MB. CD/DVD has reasonable sequential I/O but very slow seek/access speeds (as you have noted), so it's fast to refill the buffer. You just need the buffer to be large enough that it covers a few seconds to allow the disk to spin up if needed, and seek if already spun up.
One thing to try is compression. Loading a zip file off the drive, for example, will take less time but require more CPU time to process. If lossless compression is possible then that may be worth inspecting. Understanding a CD drive is useful too. The drive spins at a fixed rotational velocity. This means that data on the outside of the disc loads faster than data on the inside. A burner, however, will burn data from the inside outwards so you may end up having to burn a lot of data before the "animation" to get max read speed.
When the speed at which the disc is spun is increased, data can be transferred at greater rates. For example, a CD-ROM drive that can read at 8 speed spins the disc at 1600 to 4000 rpm, giving a linear velocity of 9.6 m/s and a transfer rate of 1200 Kbyte/s. Above 12 speed most drives read at Constant angular velocity (CAV, constant rpm) so that the motor is not made to change from one speed to another as the head seeks from place to place on the disc. In CAV mode the "" number denotes the transfer rate at the outer edge of the disc, where it is a maximum.20 was thought to be the maximum speed due to mechanical constraints until Samsung Electronics introduced the SCR-3230, a 32 CD-ROM drive which uses a ball bearing system to balance the spinning disc in the drive to reduce vibration and noise. As of 2004, the fastest transfer rate commonly available is about 52 or 10,400 rpm and 7.62 MB/s. Higher spin speeds are limited by the strength of the polycarbonate plastic of which the discs are made. At 52, the linear velocity of the outermost part of the disc is around 65 m/s. However, improvements can still be obtained using multiple laser pickups as demonstrated by the Kenwood TrueX 72 which uses seven laser beams and a rotation speed of approximately 10.
Temperatures are dropping and winter is fast approaching. For most people, this simply means making sure last year's coat still fits and finding matching gloves. But for transportation professionals, colder weather means it's time to start preparing for the harsh driving and road conditions that will grip much of the Nation for the next several months. Ensuring that Americans can move smoothly and safely to their destinations in winter is not easy, given that wet and slushy highway conditions can lead to 25 percent speed reductions and an 18 percent reduction in capacity. Nor is it inexpensive. Each year, State and local agencies spend more than $2 billion on controlling snow and ice on roads and an additional $5 billion for infrastructure repair due to snow and ice damage.
