An automatic shipping lock prevents potential damage to the heads and discs that results from movement during shipping and handling. The shipping lock automatically disengages when power is applied to the drive and the head load process begins. A high-performance actuator assembly with a low-inertia, balanced, patented, straight-arm design provides excellent performance with minimal power dissipation. 4.1 Standard features The Cheetah 15K.5 SCSI family has the following standard features: • Perpendicular recording technology. • Integrated Ultra320 SCSI interface. • Multimode SCSI drivers and receivers-single-ended (SE) and low voltage differential (LVD) • 16 bit I/O data bus • Asynchronous and synchronous data transfer protocol • Firmware downloadable via SCSI interface • Selectable even byte sector sizes from 512 to 528 bytes/sector • Programmable sector reallocation scheme • Flawed sector reallocation at format time • Programmable auto write and read reallocation • Reallocation of defects on command (post format) • ECC burst correction length of up to 400. • Sealed head and disc assembly • No preventative maintenance or adjustment required • Dedicated head landing zone • Embedded servo design • Self diagnostics performed when power is applied to the drive • Zoned bit recording (ZBR) • Vertical, horizontal, or top down mounting • Dynamic spindle brake • 16,384 kbytes data buffer • Hot plug compatibility (Section 10.6.4.2 lists proper host connector needed) for LC model drives • Drive Self Test (DST) • Supports SCSI bus fairness 4.2 Media characteristics The media used on the drive has an aluminum substrate coated with a thin film magnetic material, overcoated with a proprietary protective layer for improved durability and environmental protection.

An automatic shipping lock prevents potential damage to the heads and discs that results from movement dur-
ing shipping and handling. The shipping lock automatically disengages when power is applied to the drive and
the head load process begins.
A high-performance actuator assembly with a low-inertia, balanced, patented, straight-arm design provides
excellent performance with minimal power dissipation.
