RK06/RK07 Disk Drive User's Manual - Trailing-Edge

• Mean-time-to-repair (MTTR) for emergency maintenance is improved by the inclusion of light
emitting diodes (LEDs) on the front edge of certain logic boards. The LEDs provide a service
engineer with an indication of the functionality of certain key logic areas.
• For the implementation of cartridge alignment procedures, a protection switch is available to
the service engineer to provide write protection for the cartridge and control of head velocity to
ensure alignment integrity.
• If an RK06 or RK07 Drive loses ac power, neither the drive nor cartridge will be harmed, no
data will be lost, and the format will remain intact.
• When dual-access RK06 or RK07 Disk Drives are installed, the logic allows dual-access functionality
to be tested utilizing only one of the two available controllers. This feature provides
enhanced availability for multiprocessor systems by freeing one controller for normal dualaccess
operations.

1.3 RK611/RK06 AND RK611/RK07 DISK SUBSYSTEM PERFORMANCE SPECIFICATIONS
Tables 1-1,1-2, and 1-3 are performance specification summaries for the RK611 Controller, the RK06
Disk Drive, and the RK07 Disk Drive, respectively.
1.4 OPTIONS
Table 1-4 lists the several options currently available for the RK611 /RK06 Disk Subsystem. As indicated,
each drive is contained in an H969 "dedicated" cabinet and contains all the necessary cabling,
as well as an RK06K-DC data cartridge. E models are single access and F models are dual access.
Similarly, E model RK611 Controllers are single units and F model RK611 Controllers consist of two
controllers. The RK611-C is a dual-access controller for the Disk Subsystem and a kit to convert an
RK06E to an RK06F.
Table 1-5 lists the several options currently available for the RK611 /RK07 Disk Subsystem. As indicated,
each drive is contained in an H969 "dedicated" cabinet and contains all the necessary cabling,
as well as an RK07-DC data cartridge. E models are single access and F models are dual access.
Similarly, E model RK711 Controllers are single units and F model RK711 Controllers consist of two
controllers. The RK711-C is a dual-access controller for the Disk subsystem and a kit to convert an
RK07E to an RK07F.
