  • the headers and tails are removed from each data slice at executable block 284.
  • the voice slices are concatenated together to restore or reconstruct the original sequence of recorded voice.
  • FIG. 34 is a flowchart of a voice de-noising and voice playback software module which is executed by the controller 200.

  • the recorder/player unit 100 can be modified to include a write protect feature responsive, for example, to a hole punched in the item of media.
  • the recorder/player unit 100 includes a clamping mechanism 400 (FIGs. 15-20) adapted to receive and secure an item of media in a substantially fixed position relative to the housing 102.
  • the term "substantially fixed” means sufficiently stable so that with a particular combination of electronics 142, data transfer heads 160, drive electronics 164 and items of media, an acceptably low incidence or number of data errors is observed.
  • the clamping mechanism 400 described below is mechanically coupled to the housing 102 and is optimized to secure an item of media which is planar or substantially planar. It should be appreciated, however, that appropriate modifications to the insertion slot 110 and the clamping mechanism 400 can be made to accommodate items of media that are not substantially planar. - 14 -

  • An exemplary overcenter locking mechanism 412 includes a short link 414, long link 416, and link pin 418 configured as best shown in FIGs. 15 and 16.
  • the clamping mechanism 400 further comprises a clamping mechanism engagement sensor 420 for detecting when the clamping mechanism 400 is engaged, or in its locked position.

Abstract

L'invention concerne un système et un procédé permettant d'enregistrer des données vocales sur un dispositif de stockage de données et de lire de telles données à partir du dispositif de stockage de données disposé sur un article-support, ledit système comprenant un logement, un contrôleur et une unité de transfert de données. Le logement comporte un mécanisme de blocage conçu pour recevoir et maintenir un article-support dans une position sensiblement fixe par rapport au logement. L'article-support comprend un dispositif de stockage de données. Le contrôleur est configuré pour traiter les données numérisées de manière à produire des tranches de données et des signaux de commande. Le contrôleur est également configuré pour traiter les tranches de données en vue de la production de données numérisées reconstituées. L'unité de transfert de données, positionnée à l'intérieur du logement, est connectée électriquement au contrôleur. L'unité de transfert de données est conçue pour enregistrer les tranches de données dans le dispositif de stockage de données en réponse à l'un au moins des signaux de commande, pour lire les tranches de données à partir du dispositif de stockage de données en réponse aux signaux de commande, et pour fournir les tranches de données au contrôleur.
