I just debunked this once, here again.
It is just the blue diode, not the player, stop trying to flame people
It's actually just the blue diode that's the smallest and is only 99$, not the whole player. Everyone just search for "sharp smallest dvd" and you will see the correct info... I am not calling you a liar or anything, some of these sites did have the story wrong, but it's not even feasible for a player to be 100 bucks in this amount of time.

Sharp -- the company behind the world's largest LCD panel -- just introduced the world's smallest blue laser for next current generation optical players. Right, as in Blu-ray Disc and HD DVD formats -- your choice OEMs. Measuring just 3.3-mm in diameter, the GH04020A4G semiconductor will be available in ¥12,000 ($99) sample quantities starting June 13th before ramping up for mass production later in July. The device will suck 10mW from your laptop's battery while offering at least 10,000 hours of operation before giving up the ghost.

Sharp developed an ultra-small laser diode for Blu-Ray and HD DVD drives for notebooks.
Code-named H04020A4G, the new diode has a diameter of just 3.3mm, allowing for easy implementation of it in Blu-Ray and HD DVD drives (readers) for notebooks.
The diode's low power consumption was directly related to its low operating temperature, allowing Sharp to pack the diode into a small package, with high heat dissipation characteristics. The Japanese company said that the new diode offers high reliability, allowing it to continuously operate at 10mW for more than 10,000 hours.
Sharp will start shipping samples of the new laser in June, priced at 12,000 Yen[$99 US]. Mass production is expected to start one month later, at a target production output of 500,000 units/month.
