Product Description
The
HP
C2486A/88A/90A single-ended and differential disk drives are reliable, low cost,
high capacity, high performance, random access mass storage devices. Each
product
utilizes
sputtered thin-film 3.5-inch (95 mm) disks as storage media.
The
disk drive electrical interface
is compatible with
the
industry
standard
Small Computer System Interface (SCSI-2). Figure
1-1
shows
the
major
components of
the
disk drive.
These drives incorporate an advanced Digital
Signal Processor
(DSP)
hybrid servo design
that
provides
the
flexibility and performance of a dedicated servo system
and
the
dynamic head
alignment of an embedded servo system. High capacity and fast average transfer rates are
achieved with Multiple Zone Recording.
