DIAMONDMAX VL 20 – INTRODUCTION SECTION 1 Introduction Maxtor Corporation Maxtor Corporation has been providing high-quality computer storage products since 1982. Along the way, we’ve seen many changes in data storage needs. Not long ago, only a handful of specific users needed more than a couple hundred megabytes of storage. Today, downloading from the Internet and CD-ROMs, multimedia, networking and advanced office applications are driving storage needs even higher. Even home PC applications n

DIAMONDMAX VL 20 – INTRODUCTION Conventions If there is a conflict between text and tables, the table shall be accepted as being correct. Key Words The names of abbreviations, commands, fields and acronyms used as signal names are in all uppercase type (e.g., IDENTIFY DRIVE). Fields containing only one bit are usually referred to as the “name” bit instead of the “name” field. Names of drive registers begin with a capital letter (e.g., Cylinder High register). Numbering Numbers that are not follo

PRODUCT DESCRIPTION SECTION 2 Product Description ® Maxtor DiamondMax VL 20 AT disk drives are 1-inch high, 3.5-inch diameter random access storage devices which incorporate an on-board ATA-5/Ultra DMA 66 controller. High capacity is achieved by a balanced combination of high areal recording density and the latest data encoding and servo techniques. Maxtor's latest advancements in electronic packaging and integration methods have lowered the drive's power consumption and increased its reliabilit

PRODUCT DESCRIPTION Product Features Functional / Interface Maxtor DiamondMax VL 20 hard drives contain all necessary mechanical and electronic parts to interpret control signals and commands from an AT-compatible host computer. See Section 3 Product Specifications, for complete drive specifications. Zone Density Recording The disk capacity is increased with bit density management – common with Zone Density Recording. Each disk surface is divided into 16 circumferential zones. All tracks within

PRODUCT DESCRIPTION Logical Block Addressing The Logical Block Address (LBA) mode can only be utilized in systems that support this form of translation. The cylinder, head and sector geometry of the drive, as presented to the host, differs from the actual physical geometry. The host AT computer may access a drive of set parameters: number of cylinders, heads and sectors per track, plus cylinder, head and sector addresses. However, the drive can’t use these host parameters directly because of zon

PRODUCT DESCRIPTION Cache Management Buffer Segmentation The data buffer is organized into two segments: the data buffer and the micro controller scratch pad. The data buffer is dynamically allocated for read and write data depending on the commands received. A variable number of read and write buffers may exist at the same time. Read-Ahead Mode Normally, this mode is active. Following a read request, disk read-ahead begins on the first sector and continues sequentially until the allocated buffe

PRODUCT DESCRIPTION Major HDA Components Drive Mechanism A brush-less DC direct drive motor rotates the spindle at 5,400 RPM (±0.1%). The dynamically balanced motor/spindle assembly ensures minimal mechanical run-out to the disks. A dynamic brake provides a fast stop to the spindle motor upon power removal. The speed tolerance includes motor performance and motor circuit tolerances. Rotary Actuator All DiamondMax VL 20 drives employ a rotary voice coil actuator which consists of a moving coil, a

PRODUCT DESCRIPTION Subsystem Configuration Dual Drive Support Two drives may be accessed via a common interface cable, using the same range of I/O addresses. The drives are jumpered as device 0 or 1 (Master/Slave), and are selected by the drive select bit in the Device/Head register of the task file. All Task File registers are written in parallel to both drives. The interface processor on each drive decides whether a command written to it should be executed; this depends on the type of command
