Looking at the data sheet for a contemporary Sony CD-ROM mechanism
◆ Service life of feed motor
The current consumption of feed motor must be less than initial value plus 30% after 50,000 cycles. (1cycle : innermost track → outermost track → innermost track)
◆ Service life of limit switch
The contact resistance must be less than 100mΩ after 50,000 cycles. (1cycle : innermost track → outermost track → innermost track)
◆ Pick-up slide operation
The pick-up should operate perfectly after 50,000 cycles. (1cycle : innermost track → outermost track → innermost track)
