KC mass production Disk



The KC mass production Disk is the second Duel Disk model made by KaibaCorp. It was first issued to participants of the Battle City tournament.

It is prominently used throughout the Yu-Gi-Oh! second series anime.

Characteristics
Unlike the previous Duel Disk, it did not need to be thrown. When it first appeared in the anime, sealers flew out of the Duel Disk to the sides of the dueling area to produce the Solid Vision holograms. These were removed later. In the manga the holograms were projected straight from the Duel Disk itself.

When in use, it resembles an arm blade. Monsters that are in play are placed on the five slots on the blade.

Directly underneath each monster slot is another slot for Spell and Trap Cards. If a Duelist was to activate a Set card, they would activate a button on the round portion of the disk. Another slot can open on the front end of the disk that is used for the Field Spell Card. The center of the disk includes the Main Deck and Graveyard slot and Life Point counter. The bottom part of the disk, which goes around the user's arm, also contains a retractable cable that could be attached to Dueling Arenas if one player opted not to use a Duel Disk.

History
Prior to the Battle City Tournament, KaibaCorp developed the second generation Duel Disk, the first one to be released to the public. Issued to participants of Battle City.

These Duel Disks were the only model used until Doma used the Chaos Duel Disk.

In Yu-Gi-Oh! GX these Duel Disks were used by the students at Duel Academy prior to been given the Acadamia Disks.

In Yu-Gi-Oh! 5D's, this version of the Duel Disk was used by citizens of Satellite, while the people in New Domino City used more modern versions.

Real world
The toy company Mattel produced replicas of this Duel Disk. There are a couple of notable differences between the Mattel Duel Disk and its fictional counterpart. The Spell and Trap Cards are loaded into the bottom of the blade but most notably, it cannot project holographic images.

While the toy Duel Disk was advertised as being compatible with the TCG, there are a few flaws that make this impractical:


 * Most players used card protectors to prevent damage to their cards. Cards in protectors will not fit into the Duel Disk.
 * The Deck Zone can only hold about 50 to 59 cards safely. The Academy Duel Disk can hold 65 cards in total. While most players stick to the minimum, there are those who use bigger Decks and cannot use the duel disk. Though, the new rules made a maximum of 60 cards making the limited holding capacity problem moot.
 * The Graveyard can only hold about 20 cards. This would present a problem when playing against someone who relies on running an opponents Deck out.
 * No place for Fusion Monsters or cards that have been removed from play. (This is also true in the anime, as any removed from play cards are often seen placed into the duelist's pockets.)
 * The Life Points counter can only go up to 9990 life points. While both players start with 8000, 4000 or 2000, it could rise to 9000 or 10,000+ Life Points due to card effects. The reason for the zero at the end is because while there are four buttons on the disk, only 3 of them change the counter, the last one lights up the display. This also serves the problem that some cards can cause the Life Points in the ones place to be a number different than zero.
 * The way the duel disk moves from stand-by to in use is also different. In the anime, the Graveyard is locked over the Deck and the two field parts are retracted into the main part of the disk. When triggered, the field parts and graveyard are unlocked and the central piece rotates the graveyard and field into play position. The toy however does not have a rotating center and the two halves of the field aren't locked in closer to the central piece. When the player triggers the toy into play mode, the smaller half of the field, which is spring loaded, is released from it's lock at the same time as the larger half which has a weaker spring, and thus, the smaller part pushes the larger part into play position.

Non-canon appearances
In Yu-Gi-Oh! 5D's World Championship 2010: Reverse of Arcadia, the player can purchase this Duel Disk from Chihiro for 5 Star Chips.
