HEAD-MEDIA INTERFACE OF STRETCHED RECORDING DISK

Noise in Disk Data-Recording Media

Measurements were made of recording medium noise in erased disks using an in-contact magnetoresistive element and an inductive head supported on an air bearing slider. Four types of coatings on aluminum disks were examined: thin, transition-metal alloy film, CrO,, FeCo particle, a n d y-Fe,O:,. Results obtained by means of three measurement techniques are in qualitative agreement and indicate t...

Dynamic characterisation of the head-media interface in hard disk drives using novel sensor systems

Hard disk drives function perfectly satisfactorily when used in a stable environment, but in certain applications they are subjected to shock and vibration. During the work reported in this thesis it has been found that when typical hard disk drives are subjected lo vibration, data transfer failure is found to be significant at frequencies between 440Hz and 700Hz, at an extreme, failing at only...

Synergistic Memory Management and Disk Scheduling in the HYDRA Media Stream Recording System

Recording Characteristics of High-Density Thin Optical Disk Using Near-Field Optical Recording

Several integrated broadcast-broadband services, such as Hybridcast, have recently been launched which allow viewers to receive content via the airwaves together with additional information about the content via the Internet. By sharing personal preferences such as viewing histories with service providers, viewers can expect more attractive and personalized services. Viewing histories used for ...

Hard-disk Recording and Editing of Digital Audio

Hard-disk recording of digital audio has moved from the domain of university research projects into the mainstream of commercial professional audio. This paper attempts to define a vocabulary for discussing the differences between different approaches to hard-disk recording, and to categorize these approaches. In the process of so doing, a number of related topics will be discussed. These inclu...
