1. Loading
Of the switches SW-A and SW-B, the switch which de-
tects LH first is referred as a base switch. And then, if
the system detects LH at another switch (SW-A or
SW-B) within 3 sec, the system outputs a signal to
LOAD, FWD, and BWD, and rotates the motor in the
loading direction.
After starting of the loading, SW-A or SW-B enters op-
eration to detect of HL. When the system detects L>
H at SW-C while both SW-A and SW-B go L, the system
understands the disc size is 12 cm and continues the
loading. But, when it is not detected the system under-
stands an 8 cm disc is loaded and enters the eject opera-
tion.
In case of 12 cm disc, the system detects HL at SW-D
and completes the loading operation.
Monitoring time for switches executing the timing chart is
shown on the timing chart. if the system can not detect
for that time, it assumes a loading error exists and ex-
ecutes the eject timing chart after waiting of 30ms.
