Abstract: A method and system for providing incentives to the players of a slot machine to continue to use the slot machine. A ticket dispenser capable of being integrally coupled with a slot machine is provided. The ticket dispenser includes a ticket dispensing unit for dispensing tickets, and an interface for controlling the operation of the ticket dispensing unit in response to certain output signals from the slot machine. The interface controls the ticket dispensing unit to dispense tickets according to predefined criteria, e.g., when the number of coins bet equals a predetermined number. The dispensed tickets can then be redeemed for prizes, utilized for additional gambling, and/or used for whatever reward purposes the casino decides.

Abstract: A magnetic disc memory unit is presented wherein a pair of read/write heads are on a pivot arm which is belt driven by a stepper motor. The read/write heads move in an arc, and they retract to a landing position fully off the disc when the unit is shut down. The unit incorporates several features to overcome or minimize vibration and temperature problems so that the unit is suitable for operation in extreme vibration and temperature environments and in all attitudes. These features include, but are not limited to, a rotary table and a rotary mounted spindle made from different materials and joined by a cryogenic joint; pre-loaded elastomeric "O" rings; an electrically conductive ball used for grounding the disc support to the housing; and a single continuous split belt connected between the output of the stepper motor and the pivot arm.

Abstract: A magnetic disc memory unit is presented wherein a pair of read/write heads are attached to and driven by a continuous belt driven by a stepper motor. The read/write heads move linearly, and they retract to a landing position fully off the disc when the unit is shut down. The heads carriage structure is counterbalanced by a counterbalance assembly to allow operation at all altitudes and minimize vibration and shock problems.
