An algorithm constructed to permit correction of certainerrors occurring in an acceptable expression.Error Detection and Correction.Electromagnetic Interference. Operational interference of a device caused byelectromagnetic field generated by another device or coil.Electrically Programmable Read-Only Memory. A type of read only memory.Electrostatic Discharge. A sudden transfer of static electricity. Damage canoccur to static sensitive components (printed circuit assemblies) if a handlerdoes not eliminate the ESD potential before touching components.An abnormal and correctable condition that occurs during normal operation.Any controlling interface connecting a host to the LaserDrive.A malfunction from which the LaserDrive cannot recover without manualintervention.Control software residing in read only memory.Field Replaceable Unit. A subassembly or component which can (ifmalfunctioning) be removed and replaced in the field.The preformatted area of each sector on a disk.Suffix used to denote hexadecimal values (e.g., 7FH is a hex value).Host computerThe hardware (printed circuit assembly) and software necessary to interfacethe host central processing unit to an external device.Sector identification preformatted in the media header field.This is the portion of the LaserDrive which consists of the WOODI PCA.A SCSI-2 device (usually a host system) which requests an operation to beperformed by a Target.Illustrated Parts Breakdown. Located in the Hardware Maintenance Manualand consisting of illustrations of all FRU’s with an accompanying parts list.Controlled seek during which the tracking actuator moves to the previous trackat a specific sector, once per rotation, making the spiral track logically appearto be concentric circles.A forward-biased semiconductor junction used as the active (injection)medium.LaserDrive Used for references that apply to the LD 6100, LF 6600 and LF 6602.Laser PenLBA (SCSI-2)Assembly including laser diode and lenses.Logical Block Address.
